You can use the client-interfaces delay command which was introduced in 5.3.00c, 5.4.00a and later.
The client-interfaces delay command is used to set the delay after which the CCEP port has come up when a node is reloaded.
Brocade (config-cluster-TOR)# client-interfaces delay 60
Syntax: [no] client-interfaces delay <time in sec>
The configurable range for delay is from 20 to 600 seconds. The default value for delay is 30 seconds.Therefore, it works with default 30seconds evenwithout configuring the command.After a node gets reloaded, with just a Layer 2 VPN peer alone, the configured delay will wait the delay period to bring up the CCEP port.
The client-interfaces delay command is used to set the delay after which the CCEP port has come up when a node is reloaded. Thus, Spoke PW can be up earlier than CCEP port. This is seen when reloaded PE1 too.
In 5.3.00c,d, 5.4.00a,b, "client-interfaces delay" does not work with dual MPs or L2 + L2vpn configuration. In other words, it works only with single MP and just L2vpn. Also, the command works on only reloaded. It does not work with switchover on MPs. This is because switchover will keep a LAG ports up as LACP supports a hitless.
From 5.3.00e, 5.4.00c or later by DEFECT429441, "client-interfaces delay" is supported with dual MPs or L2 + L2vpn configuration. Also, it works with switchover on MPs.CCEP portis brought down during switchover in the new active module and the CCEP port willcome up again after "client-interfaces delay" timer is expired.
