Create monitor session via SNMP / change source interface

[bsieverling]

Hi I have a problem,

I want to change the source vlan for a SPAN monitor session. The issue is I don´t want to logon at every switch to change the source manually, because we change the source  many-times daily, we want to automatize the process as far as possible via SNMP.

I´d been searching some MIB´s for a solution to set the monitor session via SNMP but didn´t found anything, I hope somebody could enlighten me.

CISCO-FC-SPAN-MIB should have the oids you need.

Hi Dan,

thanks for your reply.Sorry, I forgot to mention that the Hardware is a Catalyst 4948 IOS 12.2(31r) SGA1. As far as I know is the FC-SPAN-MIB only available on Fiber Channel devices.

I have found a solution to create a span session via SNMP:

portCopyStatus.. i 4

portCopySessionNo.. i

portCopyDirection.. i < direction of traffic ; rx , tx or both>

portCopySessionType.. i

all objects are from the SMON-MIB

The problem is, I can only create local sessions. I can´t create a session with a vlan as a source interface.

This action results in an error

Reason: commit Failed

Is there a possibility to create a remote / vlan based  span session that way or is that at least the correct direction or is there an other solution.

Sorry for my bad english.

Thanks in advance.
