TO MAKE REDUNDANCY FOR THE EXISTING SETUP

[MSHERINE]

HAI,

WE HAVE A LAN SETUP WITH CAT 6509 AS THE CORE SWITCH AND 17 3424 SWITCH WHICH IS CONNECTED TO 6509 USING 1 MB GIBIC.THSI IS THE HEAD OFFICE SETUP WHERE WE HAVE ALL THE SERVERS.SERVERS ARE CONNECTED TO ONE OF THE 3524 SWITCHES WHICH IS IN TURN CONNECTED TO 6509.

IN 6509 MODULE 1-6 ARE USED. MODULE 1 AND 2 ARE SUPERVISOR ENGINE 2GE(RSP1&RSP1).MODULE 3,4 & 5 ARE WS-X6408 GBIC TO WHICH 3524 SERIES SWITCHES ARE CONNECTED. MODULE 6 IS A 4 PORT MULTILAYER SWITCH WS-X6302 MSM FOR INTER VLAN ROUTING.

3 SLOTS ARE EMPTY IN THE 6509 SWITCH.

WE ARE HAVING 7507 ROUTER TO WHICH THE CORE SWITCH IS CONNETED FOR WAN ACCESS WHERE WE HAVE ATM 34MBPS CLOUD AND 10 LEASED LINE OF 64 KPBS TO REMOTE LOCATIONS.

REMOTE SITES USERS ACCESS CENTRALISED SERVER WHICH IS LOCATED IN THE HEADOFFICE WHERE WE HAVE 6509 SWITCH.

WE HAVE 4 VLANS.SERVERS ARE ALL IN VLA N1.

CAN ANYBODY SUGGEST IS THERE ANY FLAW IN THE DEISIGN.

HOW CAN I ACHIEVE REDUNDANCY FOR THE CORE SWITCH AS WELL AS OTHER SWITCHES.IN THIS DESIGN.

Are your trunk ports in Vlan 1 and the SC0 interface.

I would create a new vlan for the servers.

Definitely move the servers to VLAN besides VLAN 1. Leave VLAN 1 for management traffic. I would suggest dual-homing the 3500XL to the 6500 for link redunancy. To have a Redundant Core, you will need to core switches, but you do have Supervisor Redundancy already. Do you have MSFCs on your Supervisors. If you do, I would suggest using those over the MSM.
