Alteon Hot-Standby Redundancy Configuration - Part 2

    This lab bases on the previous note "Alteon Hot-Standby Redundancy Configuration - Part 1". The topology of previous note is only one VLAN on both Alteon. Hot-Standby Redundancy also can be implemented on the topology that clients and servers locate in different VLANs.

Lab 2: Multiple VLANs implementation

hot-2

Active Alteon:

1. Change port 3 to be a tagged port

>> Main# /c/port 3/tag en
Current VLAN tag support: disbled
New VLAN tag support:     enabled

1. Create VLAN 2 for the server farm and add port 3 and 5 as members:

>> Main# /c/l2/vlan 2/def 3 5

VLAN number 2 with name "VLAN 2" created.
Port 5 is an UNTAGGED port and its current PVID is 1.
Confirm changing PVID from 1 to 2 [y/n]: y
Current ports for VLAN 2:        empty
Pending new ports for VLAN 2:    3
Current ports for VLAN 2:        empty
Pending new ports for VLAN 2:    3 5
Current ports for VLAN 2:        empty
Pending new ports for VLAN 2:    3 5

2. Add an interface IP for VLAN 2:

>> VLAN 2# /c/l3/if 2


>> IP Interface 2# addr 192.168.20.230
Current IP address:     0.0.0.0
New pending IP address: 192.168.20.230
Pending new subnet mask:        255.255.255.0

>> IP Interface 2# vlan 2
Current VLAN:     1
New pending VLAN: 2

>> IP Interface 2# en
Current status: disabled
New status:     enabled

3. Create a VIR for interface 2:

>> Main# /c/l3/vrrp/vr 3

>> VRRP Virtual Router 3# addr 192.168.20.232
Current IP address:     0.0.0.0
New pending IP address: 192.168.20.232

>> VRRP Virtual Router 3# if 2
Current interface number:     1
New pending interface number: 2

>> VRRP Virtual Router 3# vrid 3
Current virtual router ID:     1
New pending virtual router ID: 3

>> VRRP Virtual Router 3# sha dis
Current sharing: enabled
New sharing:     disabled

>> VRRP Virtual Router 3# en
Current status: disabled
New status:     enabled

>> VRRP Virtual Router 3# apply

4. Change the real server IP to a new one:

>> Main# /c/slb/real 1/rip 192.168.20.202
Current real server IP address:     192.168.10.202
New pending real server IP address: 192.168.20.202

>> Real Server 1 # apply

Standby Alteon:

Dump the configuration script from active switch and modify any necessary commands. Copy and Paste the script to standby switch.

The following script is the configuration of active switch of this example.

    Thanks for the great input, would appreciate if you could guide me on the Active-Active config of Alteon, the official documentation is quite tricky. email id is umairpb@gmail.com

    Hi Umair Pervez

    Actually, there is no real "Active-Active" configuration on Alteon. In the official guide, the services on two Alteon's are actually different. Anyway, I will post a configuration example next week.
