management vlan configuration between HP and CISCO

[Nico_lookingForWisdom]

Hello guys, 

i have difficulties setting up the connectivity between an old HP switch and a new CISCO C9200L-48P-4G-E L3 switch.

The cisco switch is supposed to replace another switch in our running company environment. 

First about my problems: 

• From the HP switch, i can ssh forward to any other switch except the new cisco one.
• On the HP switch i can run "sh cdp neighbors" an see the connected cisco switch, with its configured management ip adress 192.168.1.17 - if i run the same command on the cisco switch, i dont see any connected devices
• ping and way more important ssh doesnt work in either direction

The switches are directly connected on 4 ports.

Port 37 on the hp switch is wired with Port gigaEth1/0/1 on the cisco device.

Port 38 on the hp switch is wired with Port gigaEth1/0/2 on the cisco device.

Port 39 on the hp switch is wired with Port gigaEth1/0/3 on the cisco device.

Port 40 on the hp switch is wired with Port gigaEth1/0/4 on the cisco device.

Since the hp switch works with the other devices in the network i guess my mistake is on the cisco side

hp config:

hostname "MasterSwitch"
trunk 1-4 trk1 lacp
trunk 5-8 trk2 lacp
trunk 9-12 trk3 lacp
trunk 13-16 trk4 trunk
trunk 17-20 trk5 trunk
trunk 21-24 trk6 trunk
trunk 37-40 trk7 trunk
trunk 33-36 trk8 trunk
trunk 41-44 trk9 trunk
max-vlans 32

   name "Managment"
   no untagged 26-27,30-32,45,47
   untagged 25,28-29,46,48-52
   tagged Trk1-Trk9
   ip address 192.168.1.10 255.255.255.0
   exit

I dont care too much about the cdp problem, i just mentioned it because it might have something to do with the connectivity issue.

Last but not least, i'm not a network specialist and just inherited the topic so please dont blame me too much for mistakes that might be obvious for you.

Hi there,

The four HP ports are an LACP trunk, you should configure the same on the Cisco:

!
int range gi1/0/1-4
  channel-group 1 mode active
  swichport mode trunk
  switchport trunk vlan 1
!

Try adding the config and see if that improves the connectivity.

Confirm the status of the port-channel on the cisco with:

show port-channel summary

cheers,

Seb.

Hello,

i think you have misread the hp config.

Ports 1-12 are an LACP trunk,

Ports 37-40, where the cisco switch is connected are not.

Furthermore the command show port-channel is not recognized on the switch.

Switch7#show port?
port-security

Thanks for your effort tho :)

Hello

int vlan1

vrf forwarding Mgmt-vrf

[Nico_lookingForWisdom]

Hello,

i tried that but got the following error message:

Switch7(config-if)#vrf forwarding Mgmt-vrf
% Management interface VRF Mgmt-vrf supports one loopback interface only.

i tried to undo the command on the gigEth0/0 with the following error:

Switch7(config-if)#no vrf forwarding
% Management interface VRF can not be changed.

Thanks for your reply tho

Hi,

1. Can you attach following commands outputs from Cisco:

-show spanning-tree

-show int vlan 1

-show ip arp

-show mac address-table

2. From HP:

show spanning-tree

show mac-address-table

3. Are you planning to bundle those 4 links into single logical link?
