Q: How do I set a port's VLAN membership using SNMP?

A:

Using net-snmp, do c:\net-snmp\usr\bin\snmpset -v 2c -c community switchname 1.3.6.1.4.1.9.9.68.1.2.2.1.2.9 i 86 where 86 is the portname and 9 is the correct SNMP index to the switchport.

Q: How do I display the list of ports and their VLANs using SNMP?

A:

I use the SNMPWALK program, part of the NET-SNMP distribution.

To display list of ports and their VLANs:

snmpwalk -c readcommunity -v 1 switchname .1.3.6.1.4.1.9.9.68.1.2.2.1.2

To display the Cisco port description:

snmpwalk -c readcommunity -v 1 switchname .1.3.6.1.2.1.2.2.1.2

To display the port descriptions you configured:

snmpwalk -c readcommunity -v 1 switchname .1.3.6.1.4.1.9.2.2.1.1.28
