Appendix A CSG2 Command Reference
ip csg replicate
ip csg replicate
To enable high availability (HA) state replication between redundant CSG2 systems, use the ip csg
replicate command in global configuration mode. To disable state replication, use the no form of this
command.
ip csg replicate [vrf vrf-name] local-ip remote-ip base-port
no ip csg replicate
Syntax Description
Defaults Replication is not enabled.
Command Modes Global configuration
Command History
Usage Guidelines The ip csg replicate command enables stateful replication of the CSG2 state data structures, such as the
CSG2 User Table.
To enable replication of session and flows, use the replicate command in CSG2 content configuration
mode.
Using two separate commands to enable CSG2 replication allows for synchronization of subscriber and
quota states independent of per-flow synchronization.
Examples The following example shows how to enable CSG2 replication to a peer using local IP address
10.10.10.1, remote IP address,10.10.10.2, and UDP ports 2000 through 2005:
Ip csg replicate 10.10.10.1 10.10.10.2 2000
vrf vrf-name (Optional) Virtual Routing and Forwarding (VRF) table which the redundant
CSG2s are to use when sending state synchronization messages.
local-ip Local IP address on the CSG2 used as the source IP address for outgoing state
synchronization messages, and as the listen IP address for incoming state
synchronization messages. You must configure this IP address on the local CSG2
as either an interface or as a secondary IP address.
remote-ip Remote IP address used as the destination IP address for outgoing state
synchronization messages.
base-port User Datagram Protocol (UDP) port number used as the source and destination
port for state synchronization messages.
The specified port number is the first of six sequential UDP ports that the CSG2
uses for state synchronization. For example, if you specify port number 2000, the
CSG2 uses ports 2000 through 2005 for state synchronization.
