I suggest you remove the 'switchport access vlan 7' from your trunk, and remove 'switchport trunk native vlan 7' from all interfaces. Although this isn't necessarily a problem, pick one. You haven't given me any command output from the Brocade so I am running blind there.Īs an aside, you have switchport access and switchport trunk configurations on all your ports. Where did FastEthernet 3/0/48 come from? it wasn't in your original configuration. Once you recreate VLAN 7, this should show as line protocol up. If it is a client then you may have removed VLAN 7 elsewhere or you might have to create it on a different switch (a VTP server) Research and check the VTP configuration on the switch. Ensure there is a spanning-tree instance for VLAN 7 and it appears on the trunk between them. Start by recreating VLAN 7 on the Cisco and on the Brocade. That will likely show as line protocol down. Did it stop when you deleted VLAN 7 somehow or somewhere? And I think what you are saying is that the ping worked between the switches for 'a while' (you still haven't defined that) and then stopped. All your interfaces seem to be configured for VLAN 7 but it doesn't exist, at least on the Cisco. Both switches show port are up, but can't ping form either. The Brocade switch port used is port 1/1/48Ĭommunications worked for a while but are now not working. The Cisco switch port used is port 1/0/48 UNIT 1: compiled on at 21:57:32 labeled as ICX64R08030c We are trying to connect a Cisco 3750-48 to a Brocade ICX6450 switch.
