Stack Configuration and Deployment Recommendations

Stack Configuration and Deployment Recommendations

Feature Limitations

Version restrictions:
  • When multiple switches set up a stack, member switches will synchronize the running version of the master switch. If a member switch does not support this running version, it will restart repeatedly.

MAD specifications:
  • You can configure a maximum of eight direct detection links for each member switch in a stack.
  • You can configure the relay mode on a maximum of four Eth-Trunks in a stack.

After multiple switches form a stack, the following features cannot be configured in the stack:

  • Y.1731 one- and two-way frame delay measurement
  • N:1 VLAN Mapping

Deployment Recommendations

  • Connect a stack to other network devices using an Eth-Trunk and add one port of each member switch to the Eth-Trunk.
  • When a stack connects to access devices, configure ports directly connected to terminals as STP edge ports to prevent STP re-calculation when the ports alternate between Up and Down states. This configuration ensures normal traffic forwarding.
  • If storm control needs to be configured on many ports, replace storm control with traffic suppression to save CPU resources.
  • If port security needs to be configured on many ports, replace port security with MAC address learning limiting to save CPU resources.
  • Loops may occur on a network to which a stack connects. Run the mac-address flapping action error-down command to set an interface to the error-down state when MAC address flapping is detected on the interface. This improves system processing performance and allows the peer device to detect that the interface becomes Down. Additionally, if the peer device has redundant links, traffic can be rapidly switched to a normal link.
