Neighbours IP Address

[hafiz]

Hi guys,

I'm facing a small issue here. I'm trying to find the neighbor switches IP address that connect to my core switch. I have tried to use command "cdp" but no ip appeared.

I have tried to enable lldp on my core switch however no ip appeared also.

Is there anything that I must configure so that I can see all the IP addresses that connect to my core switch?

Thank you in advance

You need to configure IP addresses on the vlans on both switches. Then you'll see that info with show edp port <> detail.

The command
show edp ports all detailshows all IP addresses configured on VLANs of EXOS neighbor switches with EDP enabled.

Thanks!

Hafiz,

EXOS v12.0 does support the advertisement of management address information through LLDP. Now, you must understand that this IP address is the one configured in the mgmt vlan. If you don't have al IP address configured for the mgmt vlan, then the switch will send the system MAC address instead...

Then, the show lldp neighbors detailed command will show the management address of each neighbor.

Hi,

you should consider the use of LLDP. This is really nice in mixed-vendor environments, since most networking gear (even from Cisco) and many servers support LLDP.

To show all detected neighbors in detail:
show lldp neighbors detailedYou can (and usually should) enable additional information sent via LLDP:
enable lldp ports configure lldp port advertise port-description configure lldp port advertise system-name configure lldp port advertise system-capabilities configure lldp port advertise management-address
I have just verified that the above configuration is available in EXOS 15.3, I do not have earlier versions available to check.

Br,
Erik
