[GTER] IGMP Cisco

[Anísio Neto]

Pessoal,

Tenho dois Cisco 3360G interligados através de um Trunk em cima de
um Port-channel com duas fibras, em cada um dos switchs tenha uma porta na
VLAN4, elas se comunicam sem problemas (unicast), mas coloquei um serviço
que está utilizando IGMPv1 nessas portas. Me parece que o IGMPv1 não está
passando pelo Trunk, segue alguns Shows:
