Displaying software resource usage for VLANs
System Parameters | Default | Maximum | Current | Configured |
| 512 | 8192 | 300 | 300 |
The IGMP snooping mcache contains multicast forwarding information for VLANs. To display information in the multicast forwarding mcache, enter the show ip multicast mcache command.
device#show ip multicast mcache
Example: (S G) cnt=: cnt is number of SW processed packets
OIF: e1/22 TR(1/32,1/33), TR is trunk, e1/32 primary, e1/33 output vlan 10, 1 caches. use 1 VIDX
1(10.10.10.2 239.0.0.3) cnt=0 OIF: tag e2
age=2s
Syntax: show ip multicast mcache
The following table describes the output of the show ip multicast mcache command.
FieldDescription
(source group) Source and group addresses of this data stream. (* group) means match group only; (source group) means match both.
cnt | The number of packets processed in software. Packets are switched in hardware, which increases |
| this number slowly. |
|
|
OIF | The output interfaces. If entire vlan is displayed, this indicates that static groups apply to the |
| entire VLAN. |
|
|
age | The mcache age. The mcache will be reset to 0 if traffic continues to arrive, otherwise the mcache |
| will be aged out when it reaches the time defined by the ip multicast |
|
|
uptime | The up time of this mcache in seconds. |
|
|
vidx | Vidx specifies output port list index. Range is from 4096 through 8191 |
|
|
The vidx is shared among mcaches having the same output interfaces. | |
| number of mcaches using this vidx. |
