In the primary 3750:-

interface vlan xx

ip address y.y.y.y z.z.z.z

standby vv ip address w.w.w.w

standby vv timers 1 3

standby vv priority 240

standby vv preempt

ip route 0.0.0.0 0.0.0.0 <>

In the secondary 3750:-

interface vlan xx

ip address t.t.t.t u.u.u.u

standby vv ip address w.w.w.w

standby vv timers 1 3

standby vv priority 200

standby vv preempt

ip route 0.0.0.0 0.0.0.0 <>

Also make the primary 3750 the spanningtree root. connect backup connections to the

secondary 3750 and configure as the alternate spanningtree root.

In the primary 3750:-

spanning-tree vlan 1-1024 root primary

In the secondary 3750:-

spanning-tree vlan 1-1024 root secondary

xx = vlan number

y.y.y.y = ip address , i.e 192.168.1.253

z.z.z.z = subnet mask, i.e 255.255.255.0

vv = vlan number

w.w.w.w = standby ip address, i.e 192.168.1.254

t.t.t.t = ip address, i.e 192.168.1.252

u.u.u.u = subnet mask, i.e 255.255.255.0

w.w.w.w = stnadby ip address, i.e 192.168.1.254

np - glad to help.

Once again would it be better ,if i use only Switch Stack method for the two 3750 instead of HSRP?

You could do that - but what if you have a power or cable failure, your whole stack is a single point of failure?

It's really up to you on how inportant up-time is for your organisation?

thanks for your advice
