Cisco Uplinks connected to F5
I have two F5 connect by HA Also I have Cisco Stack Switch 3850 connect to F5 by 2 uplinks fiber
I configure switchport mode access in cisco to pass only one vlan to f5 that I need.
conf t
int te1/1/1 Switchport mode access switch port access vlan 2020 spanning-tree portfast
int te2/1/1 Switchport mode access switch port access vlan 2020 spanning-tree portfast
int vlan 2020 ip address 10.0.10.254 255.255.255
issue: When I disconnect one of uplinks from cisco to f5 I have wait 7 seconds for failover to another link. after that both uplinks comes down. need to disconnect the uplinks physically.
Please help and correct my mistakes.
Thanks a lot
With my regards,
With both links connected, do a show interface te1/1/1 and show interface 2/1/1. Do both ports show up or a different status?
Do a "terminal monitor" if you are logged in via VTY.
Pull Te1/1/1, what does Te2/1/1 now say? Did any information regarding Te2/1/1 show during the process of the F5 flipping.
Shutdown Te2/1/1 and re-enable the port with Te1/1/1 still disconnected. Does Te2/1/1 status show up? Does this port work? If not, move Te2/1/1 cable to the port on the F5 that Te1/1/1 was plugged into, does it work now?
Move Te2/1/1 back to the original F5 port is was on, plug Te1/1/1 back in. Verify F5 port configuration on Te2/1/1 peer is properly configured.
