1. Check all physical connections. It is a straight cable from the CS to the Switch, and a
rollover twist from the wall box to the switch (1-7,2-8).
2. Check to see if your atmarp entries are in the ARP table on the CS. ( ./atmarp if you
are already in the /usr/local/sbin directory)
• Add an atmarp entry
root@cs1 11:11:14 (4) [~] # atmarp -s 192.168.2.50 0.0.34
• View an atmarp table
