Deployment Differences Between a Standalone AC and an ACU2
Different from a traditional standalone AC, an ACU2 is a value-added service card of a modular switch. It can be installed in any LPU slot of a modular switch to provide the WLAN AC function.
As shown in Figure 2-3, an ACU2 is installed on a modular switch, and internal interfaces XGE0/0/1 and XGE0/0/2 of the ACU2 are connected to internal interfaces XGE1/0/1 and XGE1/0/2 of the switch, respectively. The switch can be connected to an AP directly or through another network device.
The switch is connected to the ACU2 through XGE1/0/1 and XGE1/0/2, in which the first digit 1 indicates the slot ID of the ACU2 on the switch. XGE1/0/1 indicates that the ACU2 is installed in slot 1 of the switch. If the ACU2 is installed in slot 2 of the switch, the switch is connected to the ACU2 through XGE2/0/1 and XGE2/0/2.
To increase the link bandwidth and improve the link reliability between the ACU2 and the switch, add the XGE interfaces connecting the ACU2 and the switch to Eth-Trunk interfaces. Otherwise, only XGE0/0/1 on the ACU2 can be used, and XGE0/0/2 remains Down.
Procedure
- Configure the ACU2.
- After you run the connect slot command, the command output varies according to the version. Perform operations as prompted.
- To log in to the ACU2 on the standby switch in a CSS, run the local-telnet command on the MPU of the master switch to log in to the standby switch, and then run the connect slot command to log in to the ACU2.
