Hello
I installed new 2 SUP720/6513 with native IOS 12.2(17b)SXA. As access switch I used C3550-48 with IOS 12.1(19)EA1a. This a configuration for an access-port:
interface FastEthernet0/1
switchport access vlan 1506
switchport mode access
switchport voice vlan 1505
no ip address
duplex full
speed 100
service-policy input VoIP-Trust-Pol
auto qos voip trust
no cdp enable
spanning-tree portfast
The HSRP is running on the distribution switches.
It seems to be that all running fine. Now I find some unknow HSRP paket with a sniffer.With debug standby I could see "redirect adv in" messages when the unknown HSRP packet appear. Have someone get the same symptom or can the unknown HSRP packet produce a critical problem?
