MA5200F version: MA2.10-7138 (independent of version)
Symptoms: MA5200F HGMPV2 manages the lower layer switches. In cluster mode, execute auto-build command, and the switches can be found. When attempting to add them, it prompts no switch is added.
1. Log into MA5200F and execute display current-configuration command to check the configurations; no problem is found.
2. Execute display ndp command, and each interface of MA5200F enables NDP, and the interfaces can learn the information of switches.
3. Enter cluster mode, and execute auto-build command; the switches can be found, but no one can be added.
4. According to the configurations of the switch, it is configured with SUPER password; delete the password, and then add the switch, but it fails again (note: when the switch is configured with super password, it needs to add the MAC of switch manually when adding switches to cluster at MA5200F, and enter the password the same as the super password at the switch; if it is added through auto-build, the switch cannot be configured with super password for successful adding because MA5200F cannot enter the same password as that at switch).
5. Check the configurations of switch, and it is configured with L3 interface address of non-VLAN1. Because it is L2 switch, it supports one L3 interface only. Thus, the cluster address at MA5200F cannot be flooded to the switch, and the adding fails.
6. Delete the L3 interfaces at the switch, and execute auto-build command at MA5200F; the switch can be added successfully. The problem is solved.
The default VLAN of HGMPV2 is VLAN 1. For one L2 switches that support one L3 interface, if the L3 interface is set to vlan1, configure cluster at MA5200F to manage the swtich because vlan1 can support cluster interface and L3 interface. At the switch, executing display interface vlan-interface 1 command can find it. However, if non-one L3 VLAN is set, the cluster IP cannot be flooded at vlan1, so it fails to add the switch.
