2530 Aruba switch port fail over

[sunilkumar19]

Hi,

I have 2530 switches connected between our two offices where the distance is about 200 metres, currently we are using fiber cable as uplink between this two offices, this is the only single point of failure.

Hence we have decided to use wireless point to point connection as backup for fiber, the challenge i am facing here i can't connect both fiber and wireless uplink cable in same 2530 switch, it is creating loop sometimes in the network and causing network disconnection.

Is there a way to configure port/Link failover in both switches...for ex : when fiber port uplink goes down the wirless P2P port should be able to send packets to gateway or destination.

Thanks in advance.

Regards,

Sunil Kumar

Hi Sunil,

Add below command in both the switches and confirmed.

"spanning-tree mode mstp"

Also refer https://www.arubanetworks.com/techdocs/ArubaOS_74_Web_Help/Content/mas_guides/mstp/MSTP.htm

Please confirm the solution once implemented.

Thanks,

Hi Shiju,

Thanks for your reply,

Forgot to mention that we have configured 3 vlans and tagged on the intreface will the vlan traffic also get included in MSTP ? or do we need to create separate tagging for packets to flow.

tagged vlan IDs

Vlan -2,3&4 on interface 10-24

Untagged vlan Id is Vlan-1 on interface 10-24 

Uplink interface in Port-24.

Please help!

Hi Shiju,

I have applied the command and connected the P2P cable, getting request time out to gateway and network is disconnected.
