Connecting 2960xr OOBM port to 4507 inband management VLAN SVI

[josephrshelton]

I have a 2960xr switch with an out of band management interface installed.

The out-of band interface is assigned an IP address that is within the IP address range on the management VLAN on my 4507 core switch.

I would like to connect interface gi7/36 on my 4507 core switch to the oobm port on my 2960xr switch.

When I connect the 2960 oobm interface to the 4507 switch port, the connection does not establish.

I am not sure what is preventing the connection for establishing.

Below is the interface configuration:

4507 Config

interface Vlan100
 description Management VLAN
 ip address 192.168.1.2 255.255.255.0
 no ip proxy-arp
 no ip route-cache

interface GigabitEthernet7/36
 description Link to 2960 oobm interface
 switchport access vlan 100
 switchport mode access
 no cdp enable

2960 Config

interface FastEthernet0
 ip address 192.168.1.14 255.255.255.0
 no cdp enable

For argument sake, if I configure the 4507 interface as a routed interface, the connection establishes. Everything works fine.

However, that's not the configuration I want to use.

I would like to connect the oobm to an switchport interface that is assigned to my management VLAN.

What could  preventing the connection from being established using this configuration?

I appreciate your responses.

should g7/36 not be in vlan 100 ? your telling it to be vlan 86 but the oobm port is ip range for vlan 100 , if there directly connected should be in same vlan ip range

[josephrshelton]

that was a typo.

interface GigabitEthernet 7/36 is on vlan 100.

ok cool then your configs good something else is causing it , can you post the show int g7/36 switchport ,sh spanning-tree vlan 100 and if layer 3 4507 show spanning-tree int vlan 100

On 2960 show interface f0

Can you ping both ips from there own local device say when directly consoled to either switch

Check sh mac address-table interface g7/36 check its mac is complete do the same for f0 , check the layer 3 device which is prob your 4507 that the macs have resolved to an ip at l3 too

You don't also have a VLAN100 SVI on the 2960 do you? If so, that won't work.

Also remember the OOB interfaces use their own VRF. Any commands you run from the 2960 need to specify to use that VRF in order to use that interface.

Also, if the device trying to reach the OOB interface is anywhere other than on VLAN 100, you need to add a default route for the 2960's management VRF.
