Packet trace

When a policy list file is downloaded to the Brocade Virtual ADX, messages to indicate download
progress are printed on the console. By default, when a policy list file is downloaded through a
Telnet or SSH session to the Brocade Virtual ADX, these messages do not appear on the Telnet or
SSH session. To monitor the download progress, you need to enable packet trace using the
following command.

Virtual ADX#ptrace term

TABLE 12

Error messages

Message

Description

BP sync msg

The number of messages that it took for the MP to synch the downloaded PBSLB
table to the BP (The download itself is staggered, so it is done in multiple passes).

BP Sync fail

The number of messages (mentioned above) that failed successful transmission. In
the event of a failure, the message is sent again.
If BP sync fails, the MP will try to push down the PBSLB table to the BPs again after
100 ms. This process continues until the BP synch is completely successful. On the
BP, the PBSLB tree is not populated until the download is totally successful.

Alloc err

The number of times the

Brocade Virtual ADX

was unsuccessful in allocating

memory for the PBSLB table. The device tries to allocate the entire table at once, so
if there is an error, this counter can only show a value of 1.
