Hot Swap Modules

The following problems have no workaround:

Hot swapping 50-series modules may cause SEPROM and SMAC panic messages to appear in the event log. These messages are for informational purposes only and should be ignored.

When you insert a module into the switch, traffic may be affected for up to seven seconds while the module performs its hardware diagnostics.

IGMP Group Membership Table

Problem:The IGMP Group Membership Table does not display all members when viewed from the Web Agent if the members are on different interfaces.

Workaround: Use the following CLI command in User mode to view the members of IGMP groups:

> show ip igmp groups

Intelligent Multicasting

The following problem has no workaround:

Layer 2 Multicast data is not forwarded on slot 17 in the P882 chassis.

Problem:Intelligent Multicasting can block protocols to non-multicast routers. If you have enabled Intelligent Multicasting and have configured a VLAN to one or more non-multicast routers or multicast-capable endstations, Intelligent Multicasting configures router ports where multicast-enabled routers reside. These multicast router ports allow all multicast packets to the adjacent multicast routers. Ports connected to non-multicast enabled routers are not considered router ports and do not receive multicast traffic. The problem can arise when multiple IP multicast addresses are mapped to the same multicast MAC address, resulting in protocol packets not being sent to the adjacent non-multicast enabled routers.
