NOTE
The server pbslb tftp command must be configured before the server pbslb time-of-day or server
pbslb download-interval command, so the Brocade Virtual ADX knows which server and file name to
use in the download.
NOTE
The PBSLB time-of-day granularity is in minutes, so seconds are ignored in the configuration. For
example, if you enter time as 16:35:30, it is taken as 16:35:00.
Configuring PBSLB download interval
To configure the Brocade Virtual ADX to download a PBSLB list at a periodic interval, use
commands similar to the following.
Virtual ADX(config)#server pbslb tftp 10.10.1.101 iplist.txt 2
Virtual ADX(config)#server pbslb download-interval 20
Syntax: server pbslb download-interval interval-in-minutes
In this example, the Brocade Virtual ADX downloads the list in iplist.txt from server 10.10.1.101
once every 20 minutes. If it encounters an error, it retries two times.
PBSLB syslog messages
Messages similar to the following appear whenever autodownload PBSLB is executed.
Aug 15 21:23:59:I:PBSLB config file 5mil-2.txt downloaded from TFTP server
172.20.1.6 -->
The preceding line indicates success.
Aug 16 13:30:03:A:FAILED to download PBSLB config file 5mil-2.txt from TFTP server
172.20.1.6 -->
The preceding line indicates failure.
Aug 16 14:20:59:W:RETRY download of PBSLB config file 5mil-2.txt from TFTP server
172.20.1.6 -->
The preceding line indicates a retry.
Displaying PBSLB entries
You can display one or more entries in the currently loaded policy list. To display an individual policy
list entry, enter a command such as the following.
Virtual ADX#show pbslb 10.10.1.101
IP address Mask Server Group ID
10.10.1.101 128 11
Syntax: show pbslb ip-address
The ip-address variable specifies the IPv4 address of the entry in the currently loaded policy list
that you want to display.
The show pbslb command displays the entry in the policy list that corresponds to the specified IP
address. If no entry is found for the specified IP address, no output is displayed.
