Switch login

[yaredo70]

I'm getting this message repeatedly when I'm trying to log in with a username and password on a switch.

%IGMP_QUERIER-4-SAME_SRC_IP_ADDR: An IGMP General Query packet with the same source IP address (X.X.X.X) is received in VLAN 999 on port Po2

I Don't have any information on how the switch is configured.

Any solutions?

Hello @yaredo70 ,

the message says that an IGMP query messages using the same source IP address of the SVI interface VLAN 999 is received on port-channel 2.

We can say that the local device is configured either as IGMP querier for VLAN 999 or as a full multicast router for the same VLAN (Ip PIM )

The message can be the result of two different issues:

a) there is another device with duplicated address in the same VLAN sending IGMP queries (the igmp querier function is not able to elect a designated device, PIM is able to elect a PIM DR)

b) the device is actually receving back its own IGMP queries and this can the sign that a bridging loop is happening in VLAN 999

Hope to help

Giuseppe

Thank you, Giuseppe. 

I'm also suspected the second one looping is happening but I can't even get into the see the configuration because I'm not able to put username and password on the login screen, it started automatically when you open putty.
