Hi all,

Just like to enquire some issue regarding Catalyst 2924

I have a pretty old Catalyst 2924 (C2900XL-H-M) switch in my office running 
IOS Version 11.2(8)SA3, however, it seems that the switch is constantly 
sending out broadcast messages as captured by tcpdump.

17:14:51.053952 0:10:b:3c:35:80 Broadcast ip 342: 0.0.0.0.bootpc >
255.255.255.255.bootps: secs:41926 [|bootp]
4500 0148 c93a 0000 ff11 f16a 0000 0000
ffff ffff 0044 0043 0134 0000 0101 0600
0000 0000 a3c6 0000 0000 0000 0000 0000
0000 0000 0000 0000 0010 0b3c 3580 0000
0000 0000 0000 0000 0000 0000 0000 0000
0000

I did not configure any IP address on Vlan 1 on the switch, but I did 
segment the switch to contain 2 more vlans (Vlan 2, 3) However, I also have 
some machines residing on Vlan 1.

However, the broadcast problem disappear after I move out the vlan1 
machines into another newly created Vlan (vlan 4), after I had shutdown 
Interface Vlan 1.

Can anyone care to enlighten me? Thanks.

Regards,
Cheeyong
