helper-address command

[Hasif VP]

Hi all,

     How can I find on which vlans are helper-address command configured? I have many devices to change helper-address.

Thanks !!!

Hi,

I think the easiest way is a "show running | include ^interface V|helper-address" from CLI.

If you want to use SNMP, the objects in CISCO-IP-IF-MIB::CiiHelperAddressEntry look very interesting.

Helper addresses will be on the default gateways of yours subnets so logon to the switch/router which is doing your intervlan routing and look there at the interface configurations.

Run "sh ip helper-address". It will show you where it's configured, but you'll still need to get into each svi to change them:
