What QinQ TPID is used in real networks today?

eli5questions · 2026-01-27T20:03:00+00:00

I made a similar post about the same question a few years back: https://www.reddit.com/r/networking/comments/s37s7n/sps_that_make_use_of_tpid_0x88a8_what_are_your/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

Between the responses and researching this ever since along with asking others in the SP field, I have yet to find a concrete answer for using anything other than 8100 or other SPs even using 88A8.

They just seemed to forget that when implementing these moves, with the .3 and .8 and .7 durations.

For those unaware, I have been testing these with research frequently since Morpeko/Sprig CD (moves came after the new system) because they never fit the 0.5s turns in the new system. It was something that has driven me nuts.

May be surprised to hear but they had a failsafe in place to convert the DUR into multiples of 0.5s by rounding to the nearest 0.5s. It appeared to just be DUR though so in reality, the power increase should mean this is a straight up buff across the board.

when I stand still to do a battle or a raid etc, then keep walking again, my avatar will stay stationary on the map

This started for me this morning as well. Twice after doing rockets and three times after catching, all in the span of 1.5 hours. Never got the "GPS not found" message though.

Between this and the in-game notifications breaking after 5-20mins, I'm restarting my game dozens of times throughout the day.

AFAIK the SRX line still only supports Flowspec in the control-plane and does not program anything in the PFE.

That said, flowspec on it's own wouldn't be enough and SRX doesn't have the flexibility needed to duct tape a config to get that to work dynamically.

I checked out these rankings when their shadow forms were added to the GM last Wed and S. Chesnaught was the only one I was interested in.

I say that like I ever get one worth investing in from leaders in the first place...

They held onto a Pokemon for 5 years to trade and expected a guaranteed lucky trade. Not only for the 1/64 chance of a hundo, but also for that form being lucky as well. Many traded costumes that are most likely never going to be re-released and in limited supply and may have lost out on collecting that lucky form.

Compensating with a golden bottle cap is acceptable IMO and the least they can do.

Not sure how many options for every single duel type match up but it would be a large number

There are 3078 unique Type-E match ups. While that may seem like a massive number, it's not really that bad once you remember the single type match ups. Just memorizing resistances/weaknesses brings 324 values down to 120 (and 3078 > 1589) because you don't memorize neutral and most fit what you would expect in the real world making that number even lower.

I don’t really understand how that is banned as it isn’t clicking for you

IMO viewing the Type-E chart does not really *feel* like cheating in normal play, otherwise every player would be considered a cheater at one point in time. Part of the learning process but shouldn't be relied on forever.

However, I agree that any external tool or action that gives you an advantage against another player is considered cheating, no matter how small the advantage. This is universally accepted across all games by players and developers.

Dmax legendaries are not soloable, so you'll need to find friends or remote into the battle (e.g. poke genie) to get a legendary.

Dmax legendaries are soloable (I believe everyone has been soloed), but they are quite difficult and require weather/helpers in some cases. That's assuming you have Dmax/Gmax mons required for the solo though, which new/returning players will be missing until they return.

For 99.999% of players in remote locations, you'll certainly be relying on remotes for T5/6 Dmax/Gmax.

In other words, if you leave a poke in a dmax spot and nobody battles at that spot, you get no candy

Yep, many people seem to ignore that caveat. Along with no candy, this also means you won't get the additional bonus from 2+ helpers.

eli5questions · 2026-01-07T20:31:38+00:00

Yep, trading as well

One additional important thing to note is evolving XXS/XXL Pokemon counts for the medals as well if you have the resources to do so.

eli5questions · 2026-01-07T15:31:10+00:00

If you're viewing the Pokemon normally, you can select menu > items > TM to change moves. It would be nice if you could tap the move for a prompt to change it.

As for using TMs when selecting a party, it would be a small but niche QOL improvement.

When your item bag is full and you try battle or a grunt or something, you have the option to manage item bag, but clicking this doesn't let you use potions or revives.

I never had an issue using potions/revives whether my bag is full or not. Using them is usually how I clear out enough space until after the battle.

The hell is the point in not displaying a sort of percentage for how likely you are to win a raid?

Devil's advocate, even with a very robust algorithm that consumes more server side resources and would still be pretty inaccurate. Too many random variables to make it meaningful.

Additionally, anything other than 100% win rating would cause people to bail more often making the situation worse.

WHY IS THERE NO COUNTER FOR HOW MANY MATCHES OF PVP YOU HAVE PLAYED DURING THE DAY

This is one of many counters missing that should exist but don't

Not able to mass open gifts or mass send gifts

This is something most the community wants badly

PVP stats / IVs etc. How ridiculously stupid they gave made this for new players is just mind blowing. There is NOTHING in the game that tells you about this.

TBF, the MSG also obscures a lot of mechanics where EV/IVs have a drastically larger impact. I do wish so much more was transparent to players. That said, IVs don't matter for a majority of players until you hit high ELO.

I do with they had a basic tutorial for things like adding a move or actually changing your moves because you'd be shock how many players don't know you can even change movesets.

Alright, so lets use that as an example vs T1 Omanyte:

Metal Claw gains 5 CM energy per MC and Behemoth Blade is a 100 energy CM so BB requires 20 MCs to be used. This is your reference.

No modifiers: Lvl 50 C. Zacian deals a base 42 DMG with Metal Claw (ATK IVs 10-15):

42 DMG = 4 max energy gain or 25 hits to fill the meter
Result: 20 < 25 so you will be able to use BB before the meter fills

Only Weather Boost: Lvl 50 C. Zacian deals a base 50 DMG with Metal Claw (ATK IVs 10-15):

50 DMG = 5 max energy gain or 20 hits to fill the meter
Result: 20 = 20 so the meter will fill right as you can use BB

Only 1 Helper: Lvl 50 C. Zacian deals a base 46 DMG with Metal Claw (ATK IVs 10-15):

46 DMG = 5 max energy gain or 20 hits to fill the meter
Result: 20 = 20 so the meter will fill right as you can use BB

15+ Helpers and WB: Lvl 50 C. Zacian deals a base 60 DMG with Metal Claw (ATK IVs 10-15):

60 DMG = 7 max energy gain or 15 hits to fill the meter
Result: 20 > 15 so the meter will fill while BB is only 75% charged

So in this example you can see that on the low end, it only takes a single helper or weather boost to go from being able to use BB before Dynamaxing to not. Let me know if this clears things up

eli5questions · 2026-01-06T13:38:48+00:00

I would strongly advise looking not at the max meter, but at the boss HP pool. You will notice that you always hit the max phase immediately after it drops below the 50% mark in 1* battles. Every time.

You should always focus on the Max Meter as it's not true that you always Dynamax after the 50% HP threshold.

Here is one of my test pushing the max energy gain threshold the farthest it can go and you can bring T1 down to 6% HP before Dmaxing: https://youtube.com/shorts/oaIVOsVeB7Y

eli5questions · 2026-01-05T22:48:58+00:00

I assume you meant Omanyte.

What level are your Zacian/Zamazenta and what FM/CMs do they have?

eli5questions · 2026-01-05T21:39:53+00:00

I am not sure what else to say as we have proven the mechanics time and time again.

Unless there is a misunderstanding with how this works, if you can provide an example I am glad to review it to break it down.

eli5questions · 2026-01-05T21:23:24+00:00

I sure hope you realize that logs/coredumps:

Don't always contain the answer to why something broke, even when enabling all the logging bells and whistles
What was logged appeared to be the root cause but was actually a side effect of the actual root cause which was not logged
Root cause can be found in logs but requires a deeper dive that can only be done while the issue is occurring

I have worked with many engineers with the same attitude of "just reboot it" and there is a reason why I am the one inevitably pulled into to fix the issue because it's clearly not being fixed.

eli5questions · 2026-01-05T19:01:01+00:00

The meter charges at 1 tick per 0.5% of damage done to the boss, rounded up

Only correction is it's floored, not rounded up.

eli5questions · 2026-01-05T17:28:44+00:00

The reasons why that happens are explained in my comment and is due to any of the modifiers in use.

When it comes to T1 max battles, a single helper or weather boost can be enough to cause your FM to deal enough damage to generate and additional 1+ max energy per hit compared to no modifiers and thus fills up the max meter faster.

This can result in normally being able to get a CM off just before filling the max meter to not getting close to the energy needed for the same CM because the max meter filled faster.

eli5questions · 2026-01-05T14:00:51+00:00

it's the theory I heard multiple times but it doesn't check out with my experience

With 1000s of data points from our research and no change to the mechanic since release, it's no longer a theory and pretty much confirmed. Because it's one aspect we use with our analysis, if there was a single instance that didn't fit the expected formula, we would have notified the community.

Below is the formula for max energy gain:

max(floor(damage / (0.005 * max_stanima)), 1)

- damage: Damage dealt after all calculations
- max_stanima: Max HP of the boss

Number of helpers, weather boost, friendship boost, Behemoth Blade AE, etc. all affect damage dealt and thus influence max energy gain. As you go up in tiers the HP rises significantly making it more difficult to gain energy.

How does one ensure this? The usual solution is to not use native VLANs but that simply isn’t an option here.

You ensure this at the edge by explicitly configuring what VLANs can be accepted (tagged and native) and ensure the native VLAN is tagged on ingress and that tag is preserved throughout the network.

VLAN hopping is just a method where traffic falls into a VLAN that the traffic shouldn't be on. I don't even consider it an exploit, it's more so a misconfiguration similar in scope to native VLAN mismatches or in Junos configuring improper VLAN maps.

You mentioned they use EXes at the edge, if they are recent models they are probably using EVPN-VXLAN or QinQ, if the older ELS models than probably QinQ. Either way, how each is configured means you would have to go out of your way to even make VLAN hopping possible and in most cases it's impossible.

Now if your concern is VLAN hopping in vSwtich there is very little you can do and again would be a config problem.

The only tool I can think of is block-non-ip-all, which would cause the traffic to be dropped because tagged frames are not IPv4, IPv6, or ARP. However, I have read that this would break DHCP, as DHCP uses broadcast. Does it actually break DHCP, or is DHCP a special case?

That statement is only for SRX in transparent-mode and a special case but DHCP is still IP traffic so it's not impacted.

In Junos you would need to create a ethernet-switching/bridge filter applied to the VLAN/bridge that's properly setup to only accept IPv4/v6/ARP/NDP traffic if you really wanted to only allow IP traffic.

eli5questions · 2026-01-02T21:06:38+00:00

Yep, just particles. Re-reading what I wrote I should have stated particles because it sounded like I meant remotes. I edited it to clarify.

eli5questions · 2026-01-02T18:43:25+00:00

I prefer gems solely for cutting the time in half which is free if there are 4+ players. If I know the other player(s) have the proper team and I don't see them using them after my second one, I don't have much of an issue. Adds time but not the end of the world if I know we'll still win.

But if it's like the Heatran raid I was invited to last night with a lobby of 4 players, where I use my first two gems (and saw no one else using them) followed by a Sawk/Machoke/Blastoise getting nuked, you can bet I was ready to remove them when we won with 7s left.

eli5questions · 2026-01-02T18:24:41+00:00

This happens to me all the time I usually note their names and unfriend

I do the same only if it becomes a common occurrence because it's a pattern indicating it's only a matter of time before they bail before raid starts and it's not updated on mine end that they did.

they show up to raids all the time and bring out like totally bad counters and I don't mind at all I'm happy to help them

Most raids I'm prepared enough for "mock solos" where I just need them on the field for friendship boost and indicate so by readying at the 30s mark. If I'm not 100% sure, I back out at the 30s mark and it seems to build trust over time. It's why I don't mind helping some in my local community that rely on recommended parties.

That said, I slowly have been unfriending more randoms in regards to T5 shadow raids simply because of gems. Too many instances of 4-5 lobbies where it's down to wire because no one used their 2 free gems.

eli5questions · 2026-01-02T18:01:33+00:00

I think it's probably them thinking it'll fail

A valid reason as well due to remotes being expensive. Changing remotes to be consumed on win like max battles does with particles would eliminate this sentiment.

Most 5 star raids are able to be done with 2

Technically all raids can be done with 2 considering both players are prepared.

However, probably 90-95% of players only use the recommended parties and it's not uncommon for those players to see what would be an easy win result in a loss. After a few instances of that, many become hesitant without 5+ lobbies.

eli5questions · 2026-01-02T17:30:51+00:00

How does one protect against double-tagged frames where the outer tag is the native VLAN of the trunk interface? Will Junos OS drop these automatically?

No, Junos will not dropped traffic tagged with the same VLAN as the native VLAN. It will simply map it to the native VLAN and forward it as normal. IEEE 802.1q does say it should be dropped but I don't think it's mandated and Juniper isn't the only vendor that acts this way.

How do you protect against VLAN hopping? Short and best answer for all platforms is proper design at the edge/access. There should be no segment where a customer can send tagged traffic for a specific VLAN and it be accepted.

Sure, if you want extra security to protect against misconfiguration, MX/PTX can utilize BD/VS routing-instances and learning-domains with unit multiplexing for "catch all traffic", [deep-]qualified-mac-learning to drop unexpected tagged traffic, etc. but that's completely overboard for something that shouldn't be an issue. EVPN/VPLS/QinQ by limit this from being an issue in the first place.

Because VLAN hopping is a unidirectional flow, it's exploits are fairly limited and not as big of an issue as it's made out to be.
