HP Comware 5 Debug Manual Vol 2

Table 19 Output from the debugging fc link evfp command
Field
Description
WWN comparison result for concurrent processes on
interface interface-name: result-code
Interface interface-name performed the concurrent
process processing, and the WWN comparison result
was result-code. The result-code values include:
• 1—The WWN of the local end is greater than the
peer end.
• 0—The WWN of the local end is the same as the
peer end.
• -1—The WWN of the local end is smaller than the
peer end.
Different access VSAN ID on both sides with
non-tagging mode
After the EVFP negotiation, the trunking mode of both
ends is Non-tagging. However, the two ends have
different access VSANs.
Table 6 describes the output fields and messages for the debugging fc link packet command.

Examples
# Enable ELP debugging. Output similar to the following example is generated when the FC device is
started.
<Sysname> debugging fc link elp
*Sep 25 10:10:34:953 2009 Sysname FCLINK/7/ELP: Launch new ELP negotiation, interfac
e Fc0/3/0, VSAN 1.
# FCLINK launched a new ELP negotiation on interface FC 0/3/0 and VSAN 1 to which the interface
belongs.
*Sep 25 10:10:34:953 2009 Sysname FCLINK/7/ELP: Encapsulate request frame, interface
Fc0/3/0, VSAN 0x1.
# FCLINK encapsulated request frames on interface FC 0/3/0 and VSAN 1 to which the interface
belongs.
*Sep 25 10:10:35:328 2009 Sysname FCLINK/7/ELP: Received ELP frame, interface Fc0/3/0
, VSAN 1.
# FCLINK received ELP frames from the peer end on interface FC 0/3/0 and VSAN 1 to which the
interface belongs.
*Sep 25 10:10:35:328 2009 Sysname FCLINK/7/ELP: Received request frame, interface Fc
0/3/0, VSAN 1.
# FCLINK parsed the ELP frames on interface FC 0/3/0 and VSAN 1 to which the interface belongs.
FCLINK found that it was the peer end that initiated the ELP request frames.
*Sep 25 10:10:35:328 2009 Sysname FCLINK/7/ELP: Concurrent process, WWN compared Res
ult: -1, interface Fc0/3/0, VSAN 1.
// Both ends initiated the ELP negotiation at the same time. The WWN comparison result was that the
WWN of the local end is smaller than the peer. As a result, the peer initiated the ELP negotiation.
