Chapter 8 Fibre Channel Commands
cfs ipv6 mcast-address
cfs ipv6 mcast-address
To configure an IPv6 multicast address for Cisco Fabric Services (CFS) distribution over IPv6, use the
cfs ipv6 mcast-address command. To disable this feature, use the no form of the command.
cfs ipv6 mcast-address ipv6-address
no cfs ipv6 mcast-address ipv6-address
Syntax Description
Command Default Multicast address: ff15::efff:4653.
Command Modes Configuration mode
Command History
Usage Guidelines Before using this command, enable CFS distribution over IPv6 using the cfs ipv6 distribute command.
All CFS over IP enabled switches with similar multicast addresses form one CFS over IP fabric. CFS
protocol-specific distributions, such as the keepalive mechanism for detecting network topology
changes, use the IP multicast address to send and receive information. CFS distributions for application
data use directed unicast.
You can configure a CFS over IP multicast address value for IPv6. The default IPv6 multicast address is
ff15::efff:4653. Examples of the IPv6 Admin scope range are ff15::0000:0000 to ff15::ffff:ffff and
ff18::0000:0000 to ff18::ffff:ffff.
Examples The following example shows how to configure an IP multicast address for CFS over IPv6:
switch(config)# cfs ipv6 mcast-address ff13::e244:4754
Distribution over this IP type will be affected
Change multicast address for CFS-IP ?
Are you sure? (y/n) [n] y
The following example shows how to revert to the default IPv6 multicast address for CFS distribution
over IPv6:
switch(config)# no cfs ipv6 ff13::e244:4754
Distribution over this IP type will be affected
Change multicast address for CFS-IP ?
Are you sure? (y/n) [n] y
ipv6-address Specifies an IPv6 multicast address or CFS distribution over IPv6. The IPv6
Admin scope range is [ff15::/16, ff18::/16].
