Hello, I was wondering, how HSRP multicast [Hello messages] are routed. For example in HSRP vers1 [224.0.0.2] and HSRP vers2 [224.0.0.102]. Taking some captures, I realized that HSRPvers1 has a TTL of 1 while HSRP vers does have a TTL value of 255. Does it mean that HSRPvers2 Hello Packets can traverse multiple hops [crossing BCAST boundaries, while HSRPvers1 is contained within one BCAST domain.   Please advise. ... View more

Hello,   Example: PC is connected to Cisco Phone and experiences sporadic network loss. Some Cisco IP Phones do support  'Cisco Discovery Protocol Enhancement for Second Port Disconnect' which allows the phone to send a message to the switch when a host unplugs from behind the phone. It has the same effect as the PC is directly connected to the switch and thus the switch would detect a link down event.   I was wondering, if Catalyst 4500 L3 Switch [Version 03.08.04.E] does support the logging of CDP messages. And what phone models do support Cisco Discovery Protocol Enhancement for Second Port Disconnect? Is it enabled by default or does it require any changes on the phone's or switch's config.   Please advise.   Thanks   ... View more

Hello, I applied the monitor capture as listed below - c4500. However, I am only able to see one-way communication, meaning only traffic leaving the source IP defined in ACL, but no incoming traffic is seen on the capture.   ip access-list extended MonCapTest permit ip host 1.1.1.1 host 2.2.2.2 Instead of using the Vlan111 interface, I applied monitor capture on the interface hosting device with IP 1.1.1.1 resulting in the same output.
