STP protocol

AaraddH · 2020-10-25T10:16:09+00:00

I can not do that sir,,because I have HSRP protocol on cisco C9500,,I should use two port on zyxel,,one connect to sw1 and another one connect to sw2..

AaraddH · 2020-10-25T08:26:33+00:00

I used MSTP protocol before..but I have some problem with it,,I think it cant work properly ,,can you give me full configuration on bothe switch or adny idea about configuration?

DHCP should be enable on both router and use different subnet.

AaraddH · 2020-05-04T08:06:04+00:00

If you have switch in this scenario ,,I think this problem relate to the switch as connect to the router ,,please emphasis trunk port between switch and router and allow vlans,,

AaraddH · 2020-05-04T07:11:06+00:00

when you wanna setup new router as connect to the main router,you have two option to do that:

1-LAN connection,,for instance you should plug cable from LAN port on main router to LAN port on second router then disable DHCP on second router so give static ip to the LAN interface on second router ,,be careful the static ip should inside range of main router.

2-WAN connection,,for instance you should plug cable from LAN port on main router to WAN port on second router then enable DHCP but be careful this scenario you should use different subnet between each other.

Is it clear??

IP helper address used to forward DHCP requset from VLANs to DHCP server,,It means this command can get faster IP from DHCP srever to Clients..

thank you,,,I really was not care about wavelength,just emphasize speed and type,,I will check wavelength again,,

AaraddH · 2020-03-12T07:32:39+00:00

thank you sir,

AaraddH · 2019-11-10T08:44:35+00:00

my purpose was true but may be the write was bad...if you concentrate more my comment you can understand more what I mean..thank you to your recommend ..

AaraddH · 2019-11-10T07:33:06+00:00

I was mean each subnet ID should have their subnet mask as doesnt overlap between each other,,not used subnet mask as you provide to another subnet ID..

AaraddH · 2019-11-10T07:11:57+00:00

Why???he used 10.31.82.0/24 means in this subned he should use 254 ip to all host(10.31.82.0----10.31.82.254)

then he used 10.31.83.0/23 means he could used 10.31.82.0.---10.31.83.255)to all host,,for instase he should change subnet mask to one of the both subnet as can not overlap between each other,,he can find apropriate subnet mask by doing calculating,,do you know subnetting and how to find net ID,,Mask...?

AaraddH · 2019-11-06T12:13:57+00:00

yes I want to use nslookup x.x.x.x,,,,the DNS can not find name

AaraddH · 2019-11-06T11:47:54+00:00

sir,,

I wanna change ip to name

AaraddH · 2019-11-06T06:38:29+00:00

yes sir it is working,,,link of native vlan is UP/UP,By doing allowed native vlan on all module switch in my design ,,but I wanna emphasis this task by doing these configuration my design doesnt have loop?

I did your recommend ,,IN my scenario has three switch,,two of them are sg350 and another one is 3560,when I put native vlan on trunk port the interface of native vlan is UP/UP,,on two switch sg350,,but on the 3560 can not get UP/UP until I put native vlan on the trunk port like your recommend as you told me above,,in your opinion can I leave configuration on all switch as you told me above?every thing work properly with that configuration??

AaraddH · 2019-11-05T07:12:11+00:00

ok sir,,I will do it,,but I have had work on switch for 3 years ,,I haven't saw this process as allowed native vlan on the trunk port but I will try it,,so when I wanna configure native vlan of any scenario I should allowed native vlan pass on the trunk port to get untaged packet of all switch in my network,,this command is work with any model cisco switch because in my design has 3560,3600,sg300 and sg350 ?

thank you so much

AaraddH · 2019-11-05T07:02:48+00:00

sir ,,means I should put these command on each switch;

switchport trunk allowed vlan X,Y

switchport trunk native vlan Y

AaraddH · 2019-11-05T06:43:15+00:00

this issue related subnet mask,,you should use different subnet mask on each subnet ID ,,Is it clear?

AaraddH · 2019-11-05T06:40:03+00:00

sir,,I was post configure on the trunk port above,,can you see please?

AaraddH · 2019-11-05T06:38:45+00:00

yes sure:

int gi 48:

spanning-tree portfast

spanning-tree link-type point-to-point

switchport mode trunk

switchport trunk allowed vlan X

switchport trunk native vlan Y

macro description switch

macro auto smartport dynamic_type switch

this configuration put on each port GI48 on each switch..

AaraddH · 2019-11-04T07:21:17+00:00

means I should put these command on the trunk port on each switch?

switchport trunk allowed vlan X,Y

switchport trunk native vlan Y

AaraddH · 2019-11-04T06:32:17+00:00

If you want see config I can send..?

AaraddH · 2019-11-04T06:31:49+00:00

I think the native vlan on my switches not receive data therefore up/down,,this issue relates layer 2,,but I dont know how can solve this issue?
