14. Disable IGMP snooping, as follows:

 

 

 

 

 

At this prompt...

 

Enter...

Notes

 

 

 

 

 

sw01(config)#

 

no ip igmp snooping

IGMP snooping is disabled to resolve communication issues

 

 

 

with the bonded Ethernet interfaces, IGMP snooping, and

 

 

 

multicast. By default, IGMP snooping is globally available on the

 

 

 

switch. With IGMP snooping, multicast packets are forwarded

 

 

 

only to the ports that have joined that multicast group. When

 

 

 

IGMP snooping is disabled, multicast packets are forwarded to

 

 

 

all ports on the switch.

 

 

 

If disabling IGMP snooping impacts network performance, and

 

 

 

if non-Cassatt Active Response applications running on the

 

 

 

Cassatt Active Response system do not use the multicast

 

 

 

functionality, disabling IGMP snooping can be done on the

 

 

 

control nodes only. In this case, do not disable IGMP snooping

 

 

 

on the switch; instead, refer to the Catalyst 3750 Switch Software

 

 

 

Configuration Guide to configure the four interfaces on the

 

 

 

control nodes to statically join the multicast group.

At this prompt...

 

Enter...

 

Notes

 

 

 

 

 

sw01(config)#

 

no ip http server

 

The HTTP server is not used and

 

 

 

 

is turned off as a security

 

 

 

 

precaution.
