IP address not visible in CDP detail

[ziqex]

Hello everyone,

I have encounter the following issue.

Two switches connected via trunk on the same native vlan.

Switch A after running cdp neighbour detail:

SW-GF-08#sh cdp neighbors detail
-------------------------
Device ID: SW-PTC-01
Entry address(es):
Platform: cisco WS-C3850-48P, Capabilities: Switch IGMP
Interface: FastEthernet0/8, Port ID (outgoing port): GigabitEthernet1/0/46
Holdtime : 136 sec

port config switch a

switchport trunk native vlan 998
switchport mode trunk
switchport nonegotiate
srr-queue bandwidth share 1 30 35 5

port config switch b

interface g1/0/46

switchport trunk native vlan 998

switchport mode trunk 

service-policy output PER-PORT-QUEUING

switchport nonegotiate

spanning-tree guard root

Any advice would be highly appreciated.

Thank you.

Hi,

You need to have an SVI on each switch to be able to see the IP

interface vlan 998

ip address x.x.x.x

Hello,

in addition to Reza's post, (obviously) make sure that Vlan 998 exists on both switches. When you do a 'sh ip int brief' the status of Vlan998 should be up/up on both switches...

If the Vlan does not exist, you need to create it:

SW-GF-08#conf t
SW-GF-08(config)#vlan 998
SW-GF-08(config-vlan)#end

SW-PTC-01#conf t
SW-PTC-01(config)#vlan 998
SW-PTC-01(config-vlan)#end

After connecting the client the management vlan status changed to up/up and the IP address is visible in the cdp neighbours detail. No configuration changed was completed.

Hello,

the management VLAN needs to be up/up indeed (just like any iinterface actually) for the IP address to become active...glad that you got it resolved.
