IGMP Snooping Commands
445
Defaults None.
Access Enabled.
Examples The following command displays querier information for VLAN
orange:
PROMT# show igmp querier vlan orange
Querier for vlan orange
Port Querier-IP Querier-MAC TTL
---- --------------- ----------------- -----
1 193.122.135.178 00:60:b9:11:e9:b4 23
The following command shows the information UNIVERGE WL Control System
displays when the querier is the UNIVERGE WL Controller itself:
PROMT# show igmp querier vlan default
Querier for vlan default:
I am the querier for vlan default, time to next query is 20
The output indicates how many seconds remain before the pseudo-querier on the
UNIVERGE WL Controller broadcasts the next general query report to IP address
224.0.0.1, the multicast all-systems group.
If IGMP snooping does not detect a querier, the output indicates this finding, as
shown in the following example:
PROMT# show igmp querier vlan red
Querier for vlan red:
There is no querier present on vlan red
This condition does not necessarily indicate a problem. For example, election of
the querier might be in progress.
Table 55 on page 446 describes the fields in the display when a querier other than
the UNIVERGE WL Controller is present.
