Hi Chubak,

Just to clarify, are you looking to connect two switches together and have them talk or are you looking for the HSRP setup. HSRP is not a standard and can only be configured on Cisco. You may be looking for VRRP. If this is true here are some articles that should be able to get you started:

Hope this helps!

Task Extreme?

Create a loopback Interface?
interface loopback 1
IP address 192.168.1.1 255.255.255.0

Create Interface vlan 101
IP address (loopback 1)

Interface vlan 102
IP address (loopback 1)

Interface vlan 103
IP address (loopback 1)


Example Cisco:

interface loopback 1
IP address 192.168.1.1 255.255.255.0

interface vlan 101
IP unnumbered loopback 1

Interface vlan 102
IP unnumbered loopback 1

Interface vlan 103
IP unnumbered loopback 1

Hi Chubak,

Based on the output you provided it looks like you are trying to create 3 vlans with vids of 101, 102 and 103. You would like them all to have loopback enabled. If this is true here are the commands below:

create vlan one tag 101
create vlan two tag 102
create vlan three tag 103

configure vlan one ipaddress 192.168.1.1/24
enable loopback vlan one

each vlan has to have its own ip address in a different subnet, like so:

configure vlan two ipaddress 192.168.2.1/24
configure vlan three ipaddress 192.168.3.1/24

Then you can enable loopback on those as well

enable loopback vlan two
enable loopback vlan three

Please let me know if this is what you are looking for.

Hi Chubak,

Cisco routers provide some special configuration options for serial interfaces. Those do not apply to Ethernet switches, neither for Cisco's nor for Extreme's. You cannot blindly copy a router configuration to a switch.
