Hi everyone,
I've a big problem with a loss of packets ICMP sent by differents hosts in differents VLAN. Here my architecture:
Core Switch : 2 Switch's C6509 (Version 15.0 (1) SY1)- Mode VSS - One lien VSL , the other link is defective
Access Switch: C3750 , Connected to Core Switch through 2 fibre optique wires
Topology: redundant ring
I've activated :
Core Switch : SPT - Snooping IGMP - Multicast routing - VSS - Snooping Querier - PIM dense mode
Access Switch : Snooping IGMP - SPT
When I send consecutive ping message I found always a missing of packets . Furthermore When I insert the "show ip traffic" command., the parameter "bad hop count" increase after a loss of packets. I've 2 hosts connected in my network and they send packets with TTL =127.
In the Core Switch I haven't configured the MEC because it gave me troubles with the packets multicast.
Could you give me any solution to solve my problem please?
Thanks very much,
