Hi,I've searched Cisco and the net in general, but I can't find any helpful information that would help me figure out what the "unknown protocol drops" are in the interface output below.Can anyone shed some light on this? #sh int f0/0FastEthernet0/0 ...

Hi all,Last weekend we ran into an ACL problem on a PIX 501 (running OS 6.3(4)). A colleague of mine needed to add a rule to the ACL applied to the outside interface. He isn't used to handling a PIX, so he did what he normally does on a Cisco device,...

For me it was obvious that by Switch1 I meant the respective Vlan interface on Switch1 (same on Switch2). My apologies for the confusion.So the default gateway of HostA is interface Vlan10 on Switch1. The default gateway of HostB is interface Vlan30 ...
