1. Hardware Requirements
- Summit X770: No option card required. The front ports 101-104 are used for SummitStack-V320
- Summit X670V: VIM4-40G4X option card required. The four ports S1-S4 are used for SummitStack-V320
2. Software Requirements
- Ensure all the switches in a stack have the same EXOS/bootrom/license level, and boot to the same partition.
3. Physical cabling of the stacking ports
- Cable stacking ports as per the below table with native 40G MPO cables and QSPF+ SR4 optics(or QSFP+ direct-attach cables).
101 ----------- S2
103 ----------- S4
102 ----------- S1
104 ----------- S3
4. Configuration Steps
- Enable "stacking-support" and reboot the switches respectively.
# enable stacking-support
# configure stacking-support stack-ports all selection native v320
- Configure stacking protocol to enhanced and reboot the switches respectively.
# configure stacking protocol enhanced
- Enable stacking on either of the switches. (All the switches will be rebooted with factory default configuration automatically)
# enable stacking
- If you need to change slot number and stack master priority, please use the below commands in the current master node and reboot the stack.
# configure stacking node-address <node-mac-address> slot-number 1
# configure stacking node-address <node-mac-address> slot-number 2
# configure stacking node-address <node-mac-address> priority 100 >>> The larger, the higher priority
# configure stacking node-address <node-mac-address> priority 90
# reboot stack-topology
* node-mac-address is the mac address of a member switch and it can be viewed by "show stacking" or "show stacking configuration".
