Stack-Local-VLANs Enhancements
Network data VLANs are shared by the stack and use the stack's virtual MAC address.
Consequently only the stack master is able to respond to messages such as ARP or ICMP
requests. One disadvantage of this is that although network administrators can ping the
whole stack to determine its operational status, such pinging will not provide status
information for individual stack members. Stack-local-VLANs provide a solution to this
problem. For command details, see vlan mode stack-local-vlan in this release note.
Stack-Local-VLAN
Operation
Each stack-local-VLAN belongs to a specific stack member, and uses that stack member’s
physical MAC address, rather than the stack’s virtual MAC address. This enables a stack
member to process stack-local-VLAN traffic directly on its own CPU, even if this is the stack
master.
This strict association of local VLAN, to specific stack member enables network
administrators to ping each stack member individually in order to monitor the health of
the entire stack, on a member-by-member basis.
Stack-local-VLANs are especially useful within networks where ping polling is used to
monitor the health of network devices.
Stack-Local-VLAN
Configuration
The following example shows a stack-local-VLAN configuration for a two member stack.
Note that overlapping IP subnets are permitted on local VLAN interfaces:
Note
This enhancement exists only on the following stackable switches: x310, x510,
and x610 Series.
Table 1-1: Configuring Stack-Local-VLANs on a Two Member Stack
Description Prompt Command
Step 1. Create the stack-local-VLANs for stack members 1 and 2
Enter global configuration
mode.
awplus#
configure terminal
Enter VLAN database mode.
awplus(config)#
vlan database
Create the stack-local-VLAN
for stack member 1.
awplus(config-vlan)#
vlan 4001 mode stack-
local-vlan 1
Create the stack-local-VLAN
for stack member 2.
awplus(config-vlan)#
vlan 4001 mode stack-
local-vlan 2
Step 2. Apply the access port mode to port 1.0.24
Enter global configuration
mode.
awplus#
configure terminal
Enter interface
configuration mode for
port 1.0.24.
awplus(config)#
interface port1.0.24
Set the port to access
mode.
awplus(config-if)#
switchport mode access
Add this port to member 1’s
local VLAN.
awplus(config-if)#
switchport access vlan
4001
Step 3. Apply the access port mode to port 2.0.24
