erx router and coa requests

[Bill Schoolfield]

This is a followup on a resolution. Posted here so someone else won't 
have to go through this pain. After trying Juniper support (they were 
clueless) and dozens of other changes, I decided that perhaps the format 
of the Acct-Session-Id value was the issue. The one used included 
interface info as well as hex encoded session number.

The router has a command to change this format to a normal decimal number:

routername(config)#radius acct-session-id-format decimal

Once set, the disconnect requests work.
