PE1950 IPMI SOL ipmitool break/SysReq VLAN problem

[Ian Durkacz]

We would like to use IPMI Serial-over-Lan (SOL) to manage remote serial 
consoles on PE1950's.

We do have SOL sessions working okay via 'ipmitool' (at both v1.8.8 and 
v1.8.9; this latter is the latest version), but have come across what 
seems like an odd problem: when using 'ipmitool sol activate' in this 
way to manage the remote consoles, the 'send break' sequence only works 
correctly (ie triggers the desired SysRq behaviour on the target system) 
if tagged VLANs have *not* been enabled on the target machine's BMC.

That is, if we do enable tagged VLANs on the target machine's BMC, the 
'send break' sequence just gets ignored - as the following screen shot 
shows:

-------------------------------------------------------------------
ipmitool -I lanplus  -H target.bmc -e [ -U root -E sol activate
[SOL Session operational.  Use [? for help]

Fedora Core release 6 (Zod)

         Supported escape sequences:
         [.  - terminate connection
         [^Z - suspend ipmitool
         [^X - suspend ipmitool, but don't restore tty on restart
         [B  - send break
         [?  - this message
         [[  - send the escape character by typing it twice
         (Note that escapes are only recognized immediately after newline.)

Can anybody comment on this, or indeed confirm the problem? Are there 
known issues to do with enabling VLANs on BMCs?

Thanks in advance.
