Configuring a dell powerconnect 54xx switch using the command line

This may work with other models of dell powerconnect switches made around 2010 or so

Configuring the time

Before you do anything if you want to display the current time from the switch's point of view:
show clock detail
To do the actual configuration you will need to enter the "configure" mode (hence the conf command below)

If you're not in the eastern timezone change the -5 value below to reflect your timezone (california/western/PST time would be -8)
If you're in europe change usa to eu, if you're elsewhere either don't use the summer-time recurring command or type clock summer-time recurring ? to see how to do a custom daylight savings/summer-time automatic clock adjustment.

conf
sntp unicast client enable
sntp unicast client poll
sntp server 10.x.x.x poll
clock source sntp
clock timezone -5
clock summer-time recurring usa
exit

Copying the running config to the startup config

copy running-config startup config

display the network settings

show ip interface

list the mac address that are on various ports

54xx: show bridge address-table
55xx: show mac address-table

I have a bash script for retreveing the port to mac address table from the switch via telnet (I personally use it under cygwin), you will have to do some edits to it, and is meant to work with dell power connect 54xx switches, though it can be edited slightly to work with dell powerconnect 55xx switches. The script is here: pc-54xx-ports-pub.sh and will output the information to a nice csv file.

if you want to get the table via snmp you can use
snmpwalk -v 1 -c public 10.x.x.x .1.3.6.1.2.1.17.4.3
