Redundancy between two 4500 switches

khaledelsaf6@gmail.com · ‎04-19-2018

Hi,

I have 2 switches 4500 switch one 4506-E with sup ws-x45-sup7L-E ios cat4500e-universal.SPA.03.10.01.E.152-6.E1

and switch 2 4507R+E with sup ws-x45-sup8-E

i need to configure redundancy between this switches .

Regards,

Khaled

Both supervisor cards, Sup7E & Sup8E, can support VSS/Easy VSS.

Hi Leo Laohoo,

I tried to configure VSS but when switch reload debug error tow supervisor not compatible

I thought you said you have two chassis with Sup8?

Reza Sharifi · ‎04-20-2018

Hi,

Since the Sups are different, you can't use VSS. You can, however, use HSRP or VRRP for redundancy.

HI Reza Sharifi,
I also tried to configure HSRP but switch one with high Priority in Active mode but can`t known any information about standby switch
and switch two with lower priority can see active switch and go to standby mode but quickly returns to standby mode

Hi,

Please post a sample config of a vlan from both switches that has HSRP enabled.

Also, post the output of "sh standby" from both switches.

this output for switch 2 when i turned on his ports

Reza Sharifi · ‎04-21-2018

Your configuration looks fine. I am not sure I understand when you say:

this output when i connected two switch direct with trunk port and switch number two no port active all ports in switch turned off

Can you explain the issue?

HTH

khaledelsafy6 · ‎04-21-2018

HI,
i means all ports turned off except the port between two core

Reza Sharifi · ‎04-21-2018

Are these core switches and do they connect to access switches? How do the access switches connect to the core? No ports should be turned off from either switch.

Can you post a diagram of your network?

HTH

khaledelsafy6 · ‎04-21-2018

I have 37 switches model 2960-x connected with two core via fiber cable all ports in Trunk mode

in core number two all ports disable when i turned it on both core come as active and network come doen

i need to active redundancy in this network
