Usage Information
Dell Networking OS supports standard access lists for the SSM range. You cannot use extended ACLs for
configuring the SSM range. If you configure an extended ACL and then used in the
ip pim ssm-range
{
access list name
}
configuration, an error is reported.
However, if you configure
ip pim ssm-range {
access list name
}
first and then you configure the ACL
as an Extended ACL, an error is not reported and the ACL is not applied to the SSM range.
Dell Networking OS-recommended best-practices are to configure the standard ACL, and then apply the ACL to
the SSM range. After the SSM range is applied, the changes are applied internally without requiring clearing of the
tree information base (TIB).
When the ACL rules change, the ACL and protocol-independent multicast (PIM) modules apply the new rules
automatically.
When you configure the SSM range, Dell Networking OS supports SSM for configured group range as well as the
default SSM range.
When you remove the SSM ACL, PIM SSM is supported for the default SSM range only.
ip pim spt-threshold
To switch to the shortest path tree when the traffic reaches the specified threshold value, configure the PIM router.
Syntax
ip pim [vrf
vrf-name
] spt-threshold [value | infinity]
To return to the default value, use the
no ip pim [vrf
vrf-name
] spt-threshold [infinity]
command.
Parameters
value
(OPTIONAL) Enter the traffic value in kilobits per second. The default is 10 packets per
second . A value of zero (0) causes a switchover on the first packet.
vrf
vrf-name
(OPTIONAL) Enter the keyword
vrf
followed by the name of the VRF to configure the
PIM router on that VRF.
