show ipv6 pim mcache

Displays the IPv6 PIM multicast cache.
Syntax
show ipv6 pim mcache [ source-address [ group-address ] | group-address | counts | dense | dit-idx dit-idx | g_entries | receiver { ethernet unit/slot/port | lag number | vlan vlan-id } | sg_entries | sparse | ssm ]
show ipv6 pim mcache counts [ source-address [ group-address ] | group-address | dense | dit-idx dit-idx | g_entries | receiver { ethernet unit/slot/port | lag number | vlan vlan-id } | sg_entries | sparse | ssm ]
Parameters
source-address
Specifies the multicast cache source address.
group-address
Specifies the multicast cache group address.
counts
Specifies the number of entries.
dense
Specifies displaying only the PIM Dense Mode entries.
dit-idx dit-idx
Specifies displaying all entries that match a specified downstream interface (DIT).
g_entries
Specifies displaying only the (*, G) entries.
receiver
Specifies displaying all entries that egress a specified interface.
ethernet unit/slot/port
Specifies a physical interface. On standalone devices specify the interface ID in the format slot/port-id; on stacked devices you must also specify the stack ID, in the format stack-id/slot/port-id.
lag number
Specifies a LAG interface.
vlan vlan-id
Specifies a VLAN.
sg_entries
Specifies displaying only the (S, G) entries.
sparse
Specifies displaying only the PIM Sparse Mode entries.
ssm
Specifies displaying only the SSM entries.
Modes

User EXEC mode

The show ipv6 pim mcache command displays the following information:

Field

Description

Total entries in mcache

Shows the total number of IPv6 PIM mcache entries.

upstream neighbor

Shows the upstream neighbor for the Source/RP based on the type of entry.

For (*,G) it shows the upstream neighbor towards the RP. For (S,G) entries it

shows the upstream neighbor towards the source.

Flags

Show the flags associated with the forward entry.

slow ports ethe

Shows the forwarding port ID of the mcache entry which is in the software forwarding path.

AgeSltMsk

Shows the slot number on which MP expects ingress traffic.

L2 FID

Shows the hardware resource allocated for the traffic switched to receivers in the ingress VLAN.

DIT

Shows the hardware resource allocated for routed receivers.

Forwarding_oif

Shows the number of outgoing interfaces of the mcache entry.

immediate_oifs

Shows the local immediate outgoing interface of the mcache entry.

blocked_oifs

Shows the PIM Sparse mode blocked outgoing interfaces.

L3 (SW) 1

Shows whether the traffic is switched or routed out of the interface.

L3 (HW) 1

The forwarding entries by using hardware.

Src-Vlan

VLAN associated with the ingress interface.

Examples

The following example displays the IPv6 PIM multicast cache.
