Default Gateway not in use
« on: April 20, 2017, 10:11:15 AM »
I have a switch that has been running in our environment for years. Recently I tried to access it and couldn't. I consoled in and found I couldn't ping the gateway or a DC controller on another subnet. I went into the IP configuration setup and found this:
IP Configuration/Setup


                 BootP/DHCP Request Mode:  [ BootP When Needed     ]


                                      Configurable          In Use       Last BootP/DHCP
                           -------------------  ---------------  ---------------In-Band Stack IP Address:  [ 0.0.0.0 ]          0.0.0.0          0.0.0.0
In-Band Switch IP Address: [ 10.10.1.55 ]       10.10.1.55       0.0.0.0
In-Band Subnet Mask:       [ 255.255.255.0 ]    255.255.255.0    0.0.0.0

Default Gateway:           [ 10.10.1.1 ]             0.0.0.0          0.0.0.0

IP Address to Ping:        [ 0.0.0.0 ]
Start Ping:                [  No ]

Does in use just point to the 0.0.0.0 0.0.0.0 route?
In any event I can't get to it over the network and I cannot ping anything from the switch itself. Yet it passes traffic.

Thanks,
Bill

Hey Bill,

Looks like Your Management VLAN isn't setup correctly. Verify which VLAN is marked as management and ensure that it is a member of a port that can be switched to reach the default gateway.

Hi Bill,

maybe "ip routing" is enabled, therefore your DefGW is not in use.
Additionally an static route default route needs to be added/activated.

And of course the Mgmt-Vlan needs to be set correctly.

Good luck

Mgm-Vlan is correct.
I'll check if ip routing is enabled, thanks.
Never needed to deal with the bootp setting in my 6 years of managing these switches but I'll try it.
Thanks
