PIM Sparse
Displaying the PIM multicast cache
To display the PIM multicast cache, enter the show ip pim mcache command at any CLI level.
Syntax: show ip pim mcache
Table 264 shows the information displayed by the show ip pim mcache command.
TABLE 264 Output of show ip pim mcache
Field Description
(<source>, <group>) The comma-separated values in parentheses is a source-group pair.
The <source> is the PIM source for the multicast <group>. For example, the following entry
means source 209.157.24.162 for group 239.255.162.1:
(209.157.24.162,239.255.162.1)
If the <source> value is * (asterisk), this cache entry uses the RP path. The * value means
“all sources”.
If the <source> is a specific source address, this cache entry uses the SPT path.
RP<ip-addr> Indicates the RP for the group for this cache entry.
NOTE: The RP address appears only if the RPT flag is set to 1 and the SPT flag is set to 0
(see below).
forward port The port through which the Layer 3 switch reaches the source.
Count The number of packets forwarded using this cache entry.

Total 2 entries
Example: (S G) in v40 (e2/3) cnt= : e2/3 is phy. of input v40, cnt: SW hit incl.
drop
HW: CAM switched, SW: cpu switched, OAR: SW one?arm?routing, VL: vlan
trunking: TR(e3/3,e3/4): e3/3 is primary trunk port, e3/4 is real out p.
FLAGS: fast/slow: could be HW switched or not
pru: pruned from upstream
frag: packet fragmented, SW forwarded unless multicast?perf configured
tag/tnnl: OIF has tagged/tunnel ports
swL2/hwL2: SW or HW L2 forwarding
age: send 1 pkt to cpu from HW switch to reset age
0L2C: no L2 CAM hash
ClSr: has client on input port, never send prune even OIF empty
drop: use cam to drop pkts if no OIFs.
