No MAC addresses in User Tracking on LMS 4.2.3

[Clement BONNAL]

                   Hello,

I have 2960 configured for SNMPv3, and LMS 4.2.3 which can poll 2960 without problem.

But in the user tracking, I can see VLAN / Port / Switch where a user is connected, but I haven't his MAC address nor his IP.

Here is the 2960 conf :

ip access-list standard SUP-ACCESS-RW

permit 192.168.20.104

ip sla responder

snmp-server group SUPERVISION-RW v3 priv read sup-view-rw write sup-view-rw notify sup-view-rw access SUP-ACCESS-RW

snmp-server view sup-view-rw iso included

snmp-server location "-------"

snmp-server contact "-----"

snmp-server system-shutdown

snmp-server enable traps snmp authentication linkdown linkup coldstart warmstart

snmp-server enable traps cpu threshold

snmp-server enable traps port-security trap-rate 1

snmp-server enable traps envmon fan shutdown supply temperature status

snmp-server enable traps storm-control trap-rate 1

snmp-server enable traps bridge newroot topologychange

snmp-server host 192.168.20.104 version 3 auth cisco-prime

snmp ifmib ifindex persist

switch# show snmp user

User name: cisco-prime
Engine ID: 80000009030004DAD2367A81
storage-type: nonvolatile        active
Authentication Protocol: MD5
Privacy Protocol: AES128
Group-name: SUPERVISION-RW

Do you know what is the problem ?

Thank you.

Hi ,

In order for the device to allow SNMPv3 vlan context-based queries to be processed, the
following must be added to the configuration for EVERY vlan that you want user tracking to
collect information on:
“snmp-server group  v3  context vlan-X” (where X
is the vlan number)
Perform the following on the switch to help show which vlans require this command:
 "show snmp context"
Solution: Configure the switch to allow vlan context queries.

I hope this will help

Thanks-

Hello,

If I have 90 vlans, I have to add 90 snmp-server .... lines on each switch ?

Is there a command to include all vlans ?

Thank you!

Hi ,

Try this command

for e.g
snmp-server group v3lms v3 priv context vlan- match prefix

this should work for you..

Thanks-

Hello,

This answer doesn't solve my problem.

I can see this morning that User Tracking is OK on 5 switchs only, and after calling the customer, I learnt that these switchs rebooted during the night.

Is there a command to reload the SNMP process istead of restart the all 200 switches ?

Hi,

Yes there a procedure to restart the SNMPD process on Nexus ,but for that you need to go to TAC.

OK,

Now I have MAC addresses but not IP addresses. (See file in attachement)

What could be the problem ?

Hi Mark,

Run a new DATA Collection ,followed by user tracking and see how it works

Thanks-
