IGMP snooping configuration
IGMP snooping configuration
Configuring IGMP snooping on a Brocade device consists of the following global, VLAN-specific, and
port-specific tasks:
Global IGMP snooping tasks
Perform the following global tasks:
• “Configuring the IGMP V3 snooping software resource limits”
• “Enabling IGMP snooping globally on the device”
• “Configuring the global IGMP mode”
• “Configuring the global IGMP version”
• “Modifying the age interval for group membership entries”
• “Modifying the query interval (active IGMP snooping mode only)”
• “Modifying the maximum response time”
• “Configuring report control” (rate limiting)
• “Modifying the wait time before stopping traffic when receiving a leave message”
• “Modifying the multicast cache age time”
• “Enabling or disabling error and warning messages”
VLAN-specific IGMP snooping tasks
Perform the following VLAN-specific tasks:
• “Configuring the IGMP mode for a VLAN” (active or passive)
• “Disabling IGMP snooping on a VLAN”
• “Configuring the IGMP version for a VLAN”
• “Configuring static router ports.”
• “Turning off static group proxy”
• “Enabling IGMP V3 membership tracking and fast leave for the VLAN”
• “Enabling fast leave for IGMP V2”
• “Enabling fast convergence”
Port-specific IGMP snooping tasks
Perform the following port-specific tasks:
• “Configuring the IGMP version for individual ports in a VLAN”
Configuring the IGMP V3 snooping software resource limits
FCX, FSX, ICX 6610, and ICX 6450 devices support up to a maximum of 8192 IGMP snooping
multicast cache (mcache) entries and a maximum of 8192 IGMP group addresses. ICX 6430
devices support up to 2048 IGMP snooping multicast cache (mcache) entries and a maximum of
4096 IGMP group addresses.
The default for IGMP snooping mcache entries is 512, with the exception of ICX 6430 devices
where the default is 256.
