Card Overview

Intelligent Stack (iStack) technology enables multiple stacking-capable devices to function as a logical device.

Before a stack is set up, each switch is an independent entity that has its own IP address and MAC address. You need to manage the switches separately. After a stack is set up, switches in the stack form a logical entity that can be managed and maintained using a single IP address. Stack technology improves forwarding performance and network reliability, and simplifies network management.

Switches can be connected as a stack using service ports or stack cards (ES5D00ETPC00).

The ES5D00ETPC00 stack card can be installed in a rear card slot of the switch models listed in Table 8-156.

Table 8-157 describes functions of the ES5D00ETPC00.

Table 8-157 Functions



Basic function

Provides two 12 Gbit/s electrical ports for stacking. The 12 Gbit/s electrical ports on multiple switches are connected using PCIe cables to set up a stack.

Topology Switches in a stack can be connected in a chain or ring topology. A link failure in the chain topology causes the stack to split. In contrast, the ring topology changes into a chain topology upon a link failure so that services in the stack are not affected. Therefore, the ring topology is more reliable than the chain topology. Figure 8-70 and Figure 8-71 show the chain and ring topologies.
When connecting stack cables, connect stack1 port of one switch to stack2 port of another switch.

Usage Constraints

The following requirements must be met to set up a stack:
  • All the member switches belong to the same series. The EI series and SI series cannot form a stack.
  • All switches have stack cards installed and are connected using PCIe cables.
  • The ES5D00ETPC00 is not hot swappable, but PCIe cables are hot swappable.
