IP Source Guard crush Catalyst 3750
 
Hello!
I try to use Catalyst 3750 with "ip source quard". When there is 2000 lines
with "ip source binding..." in config, something like this:
ip source binding 8888.2222.0001 vlan 1001 192.168.168.1 interface Gi1/0/6
ip source binding 8888.2222.0002 vlan 1001 192.168.168.2 interface Gi1/0/6
ip source binding 8888.2222.0003 vlan 1001 192.168.168.3 interface Gi1/0/6
ip source binding 8888.2222.0004 vlan 1001 192.168.168.4 interface Gi1/0/6
ip source binding 8888.2222.0005 vlan 1001 192.168.168.5 interface Gi1/0/6
ip source binding 8888.2222.0006 vlan 1001 192.168.168.6 interface Gi1/0/6
ip source binding 8888.2222.0007 vlan 1001 192.168.168.7 interface Gi1/0/6
ip source binding 8888.2222.0008 vlan 1001 192.168.168.8 interface Gi1/0/6
ip source binding 8888.2222.0009 vlan 1001 192.168.168.9 interface Gi1/0/6
....
a switch works to first reload. After reload the switch, CPU utilization is
100 %. "HULC DHCP Snoopi" process take 80-95% of utilization. There is no
infrmation about maximum "ip source binding..." lines in technical
informations for this switch. I think this is a bug i IOS.
Is there anybody who use "ipsource guard..." on Catalyst 3570 ?


Best Regards

Adam
