To use an ACL that does not exist in the group-policy list, you can use the
acl-number
argument to specify
an ACL and set its
order-value
. This inserts the ACL to the position of
order-value
in the group-policy list.
If you do not include the
order
order-value
option in your command, the ACL is appended to the end of
the group-policy list.
If you use this command multiple times on the same multicast group, the first traffic rate configuration
matched in sequence takes effect.
If the switch is an RP, disabling switchover to SPT might cause multicast traffic forwarding failures on the
source-side DR. When disabling switchover to SPT, be sure you fully understand its impact on your
network.
Examples
# Disable the switchover to SPT on the receiver-side DR.
<Sysname> system-view

ssm-policy (PIM view)
Syntax
ssm-policy
acl-number
undo ssm-policy
View
PIM view
Default level
2: System level
Parameters
acl-number
: Basic ACL number, in the range of 2000 to 2999.
Description
Use
ssm-policy
to configure the SSM multicast group range.
Use
undo ssm-policy
to restore the default.
By default, the SSM group range is 232.0.0.0/8.
You can use this command to define an address range of permitted or denied multicast groups. If the
match succeeds, the multicast mode is PIM-SSM. Otherwise, the multicast mode is PIM-SM.
Examples
# Configure the SSM group range to be 232.1.0.0/16.
<Sysname> system-view
[Sysname] acl number 2000
[Sysname-acl-basic-2000] rule permit source 232.1.0.0 0.0.255.255
[Sysname-acl-basic-2000] quit
[Sysname] pim
[Sysname-pim] ssm-policy 2000
