Compared with the link topology, the ring topology enjoys higher reliability. When a stack link
in a ring topology breaks, the ring topology becomes a link topology. The entire stack system,
however, runs normally. You are recommended to adopt a ring topology when deploying
services.
3.5 Configuring the Stacking Function on the S5700
This section describes how to configure the stacking function on the S5700.
3.5.1 Establishing the Configuration Task
Applicable Environment
To improve the interface density and forwarding capacity of a network, you can configure the
stacking function on the S5700. In this manner, you can expand the network capacity and
facilitate users' management.
Pre-configuration Tasks
Before creating a stack system, complete the following tasks:
l
Configuring the same software version for all the member switches
l
Using the devices of the same type (for example, EI devices or SI devices) as the member
switches of a stack system
The EI devices and SI devices cannot be used in the same stack system.
l
Installing stack cards on all devices and connecting the devices through stack cables
l
Ensuring that all the stack devices can be started normally
Data Preparation
To configure the stacking function, you need the following data.
No.
Data
1
Stack ID of an S5700
2
Stack priority of an S5700
3
MAC address switchover time
3.5.2 (Optional) Configuring the Reserved VLAN of the Stack
This section describes how to configure the reserved VLAN for the stack.
Context
When the default reserved VLAN of the stack is used for other services, you need to configure
a new reserved VLAN before enabling the stacking function.
