Using ELS

3.Use the net number from the previous step to determine the associated MAC address

4.In talk 6, add an ARP entry to establish a static IP address to MAC address relationship

*t 5 +p ip

IP>ping 192.9.200.1

PING 192.9.200.20 -> 192.9.200.1: 56 data bytes, ttl=64, every 1 sec.

56 data bytes from 192.9.200.1: icmp_seq=0. ttl=64. time=0. ms

Are you sure you want to reload the gateway? (Yes or [No]): Yes

(after reload, static ARP entry is active)

Additional Considerations

ELS Messages Containing IP Addresses

ELS messages containing an IP address which matches the IP address of the remote workstation will not be remote-logged, even if con®gured for remote-logging, and may appear under talk 2. These messages are discarded instead of being remote-logged in order to prevent excessive UDP packets from being sent on the network.
