rtr-port

The router ports which are the ports receiving queries. The display router ports: 1/36(120) 2001:DB8::2e0:52ff:fe00:9900 means port 1/36 has a querier with 2001:DB8::2e0:52ff:fe00:9900 as the link-local address, and the remaining life is 120 seconds.

max-resp-t

The maximum number of seconds a client can wait before it replies to the query.

non-QR

Examples

The following example shows MLD snooping information for a VLAN. 

device> show ipv6 multicast vlan 11 

Version=1, Intervals: Query=300, Group Age=620, Max Resp=10, Other Qr=605,
Leave Wait=2, Robustness=2
    router ports: 1/36(120) 2001:DB8::2e0:52ff:fe00:9900,
  My Query address: fe80::ce4e:24ff:fe6f:980 (link-local)
  1/26 has 2 grp, non-QR (passive), cfg V1
  1/26 has 2 grp, non-QR (passive), cfg V1
    group: ff10:1234::5679, life = 100
    group: ff10:1234::5678, life = 100
  1/35 has 0 grp, non-QR (QR=2001:DB8::2e0:52ff:fe00:9900, age=20), dft V2 trunk

The following example shows MLD snooping information when flooding of unregistered IPv6 multicast frames is disabled: 

device> show ipv6 multicast vlan

Summary of all vlans. use "sh ipv6 multicast vlan vlan-id" for details
Version=1, Intervals: Query=125, Group Age=260, Max Resp=10, Other Qr=255
Leave Wait=2, Robustness=2
Unregistered IPv6 Multicast Packets Flooding: Disabled.

VL500: dft V1, vlan cfg active, 0 grp, 0 (*G) cache, no rtr port, 
VL600 no snoop: no global or local config
