[c-nsp] VLANs and snmp

[Nicolai Strøm Gylling]

Hi

The standard interface information, ifIndex, ifDescr, ifOperStatus, ifAdminStatus, you can get by snmpwalk'ing .interfaces like

	Snmpwalk ip public .interfaces

For the vlan/port relationship, try looking at the CISCO-VLAN-IFTABLE-RELATIONSHIP-MIB.my MIB available from Cisco's FTP-site. 
You could start by doing a snmpwalk on the following OID(cviVlanInterfaceIndexEntry):

	Snmpwalk ip public .1.3.6.1.4.1.9.9.128

That will give you a list of the Vlan/port relationship, eg.

	enterprises.9.9.128.1.1.1.1.3.5.0 = 23, Vlan5 on ifIndex 23.
	enterprises.9.9.128.1.1.1.1.3.10.0 = 25, Vlan10 on ifIndex 25.
	...

Hello,

 

Is there a way to obtain via snmp the VLAN information of a switch (in my case, Catalyst 3524)?

 

My broader problem is the following: I would like to write a script that shows, for all ports of a switch, the following data:

*	Interface name
*	Interface description
*	Operational and administrative status
*	VLAN it belongs to

 

If could gather this via an expect script (telnet, sh int, sh vlan); but I'd prefer to do it via snmp.

 

Any ideas?

 

Vincent
