I have a 2950 24 port switch and I am trying to assign an IP to vlan1 for management purposes. To do so I did the follwoing:
When I attempt to ping something on the local LAN (10.24.64.110 for example) it fails. When I issue a sh ip arp command it shows the IP address I just attempted to ping with a hardware address of Incomplete.
Why wont my Switch communicate on the local LAN?. My config is as follows:
I also captured traffic on the local LAN and found that the switch was sending out an arp request but never seeing a reply. Since its on the local (layer 2) lan I would think the default gateway is irrelevant. Furthermore, the destination node has the correct Arp entry in its local table for the switch. It seems that the switch is filtering or unwilling to processes arp requests from the local lan. Any Ideas?
Code:
config t
interface vlan 1
ip address 10.24.64.5 255.255.255.0
no shut
