enable igmp_snooping
Purpose
Used to enable IGMP snooping on the Switch.
Syntax
enable igmp_snooping {forward_mcrouter_only}
Description
This command allows enabling of IGMP snooping on the Switch. If
forward_mcrouter_only
is specified, the Switch will only forward all
multicast traffic to the multicast router, only. Otherwise, the Switch
forwards all multicast traffic to any IP router.
Parameters
forward_mcrouter_only
−
Specifies that the Switch should only
forward all multicast traffic to a multicast-enabled router. Otherwise,
the Switch will forward all multicast traffic to any IP router.
Restrictions
Only Administrator or Operator-level users can issue this command.
Example usage:
To enable IGMP snooping on the Switch:
DES-3800:admin#enable igmp_snooping
Command: enable igmp_snooping
Success.
DES-3800:admin#
disable igmp_snooping
Purpose
Used to disable IGMP snooping on the Switch.
Syntax
disable igmp_snooping {forward_mcrouter_only}
Description
This command disables IGMP snooping on the Switch. IGMP
snooping can be disabled only if IP multicast routing is not being
used. Disabling IGMP snooping allows all IGMP and IP multicast
traffic to flood within a given IP interface.
Parameters
forward_mcrouter_only
– Adding this parameter to this command will
disable forwarding all multicast traffic to a multicast-enabled routers.
The Switch will then forward all multicast traffic to any IP router.
Entering this command without the parameter will disable igmp
snooping on the Switch.
Restrictions
Only Administrator or Operator-level users can issue this command.
Example usage:
To disable IGMP snooping on the Switch:
DES-3800:admin#disable igmp_snooping
Command: disable igmp_snooping
Success.
