R3721-F3210-F3171-HP High-End Firewalls Network Management Command Reference-6PW101

927
Description
Use spt-switch-threshold to configure the SPT switchover parameters.
Use undo spt-switch-threshold to restore the default.
By default, the device switches to the SPT immediately after it receives the first IPv6 multicast packet.
To adjust the order of an IPv6 ACL that already exists in the group-policy list, you can use the acl6-number
argument to specify this IPv6 ACL and set its order-value. This will insert the IPv6 ACL to the position of
order-value in the group-policy list. The order of the other existing IPv6 ACLs in the group-policy list will
remain unchanged.
To use an IPv6 ACL that does not exist in the group-policy list, you can use the acl6-number argument to
specify an IPv6 ACL and set its order-value. This will insert the IPv6 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 will be
appended to the end of the group-policy list.
If you use this command multiple times on the same IPv6 multicast group, the first traffic rate configuration
matched in sequence takes effect.
Examples
# Disable SPT switchover on the firewall that will never become an RP.
<Sysname> system-view
[Sysname] pim ipv6
[Sysname-pim6] spt-switch-threshold infinity
ssm-policy (IPv6 PIM view)
Syntax
ssm-policy acl6-number
undo ssm-policy
View
IPv6 PIM view
Default level
2: System level
Parameters
acl6-number: Basic IPv6 ACL number, in the range of 2000 to 2999.
Description
Use ssm-policy to configure the IPv6 SSM group range.
Use undo ssm-policy to restore the default.
By default, the IPv6 SSM group range is FF3x::/32. Here x refers to any legal scope.
This command allows you to define an address range of permitted or denied IPv6 multicast groups. If the
match succeeds, the running multicast mode will be IPv6 PIM-SSM. Otherwise the multicast mode will be
IPv6 PIM-SM.
Examples
# Configure the IPv6 SSM group range to be FF3E:0:8192::/96.
<Sysname> system-view
