Setting Stateless Ipv6 Autoconfiguration; Changing The Rbridge Id; Changing The Vcs Id - Brocade Communications Systems Brocade VDX 6740 Hardware Reference Manual

The enabled or disabled state of autoconfiguration does not affect any static IPv6 addresses that
may have been configured. Stateless IPv6 autoconfiguration and static IPv6 addresses can coexist.

Setting stateless IPv6 autoconfiguration

To configure stateless IPv6 autoconfiguration, complete the following steps.
1. Issue the configure terminal command to enter global configuration mode.
2. Take the appropriate action based on whether you want to enable or disable IPv6

Changing the RBridge ID

If you are going to have more than one switch in a fabric, each switch must have a unique RBridge
ID. The default RBridge ID for any Brocade VDX 6740 is 1. Use the vcs rbridge-id [rbridge-id]
command to change the default RBridge ID. You should be in privileged EXEC mode to run the
command. If you have made any other configuration changes you want to persist, be sure to save
your running configuration to the startup configuration before running the vcs rbridge-id command
as this command reboots the switch.

Changing the VCS ID

If you are going to have more than one VCS fabric, each fabric must have a unique VCS ID. The
default VCS ID for any VCS fabric is 1. Use the vcs vcs-id [ID] command to change the default VCS
ID. You should be in privileged EXEC mode to run the command. If you have made any other
configuration changes you want to persist, be sure to save your running configuration to the startup
configuration before running the vcs vcs-id command as this command reboots the switch.
