XGS3 Command Guide
39-55
Comment: There are three ways to learn mrouter port in MLD Snooping:
1. The port which receives MLD query messages
2. The port which receives multicast protocol packets and support PIM
3. The port statically configured.
Example: Set VLAN 100 to L2 general querier.
Switch (config)# ipv6 mld snooping vlan 100 l2-general-querier
39.8.8 ipv6 mld snooping vlan limit
Command: ipv6 mld snooping vlan < vlan-id > limit {group <g_limit> | source <s_limit>}
no ipv6 mld snooping vlan < vlan-id > limit
Function: Configure number of groups the MLD snooping can join and the maximum number of sources
in each group.
Parameter: vlan-id: vlan id, the valid range is <1-4094>
g_limit: <1-65535>, max number of groups joined
s_limit: <1-65535>, max number of source entries in each group, consisting of include
source and exclude source
Command Mode: Global Mode
Default: Maximum 50 groups by default, with each group capable with 40 source entries.
Usage Guide: When number of joined group reaches the limit, new group requesting for joining in will be
rejected for preventing hostile attacks. To use this command, MLD snooping must be enabled on VLAN.
The “no” form of this command restores the default other than set to “no limit”. For the safety
considerations, this command will not be configured to “no limit”. It is recommended to use default value
and if layer 3 MLD is in operation, please make this configuration in accordance with the MLD
configuration as possible.
Example:
Switch(config)#ipv6 mld snooping vlan 2 limit group 300
39.8.9 ipv6 mld snooping vlan mrouter-port interface
Command: ipv6 mld snooping vlan <vlan-id> mrouter-port interface [<ethernet>|<port-channel>]
<ifname>
no ipv6 mld snooping vlan <vlan-id> mrouter-port interface
[<ethernet>|<port-channel>] <ifname>
Function: Set the static mrouter port of the VLAN; the “no” form of this command cancels the
configuration.
Parameter: vlan-id: VLAN id, the valid range is<1-4094>
Ehternet: name of Ethernet port
Ifname: Name of interface
port-channel: port aggregate
Command Mode: Global Mode
Default: When a port is made static and dynamic mrouter port at the same time, it’s the static mrouter
properties is preferred. Deleting the static mrouter port can only be done with the “no” form of this
command.
