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.
