Other: How Can I Increase the Rate of Ports on the S5732-H24UM2CC or S5732-H48UM2CC?

You can apply for a license file containing the following resource control items to increase the rate of ports on the S5732-H24UM2CC or S5732-H48UM2CC:

L-1GUPG2.5G-S57H: increases the rate of 12 ports from 1 Gbit/s to 2.5 Gbit/s.
L-1GUPG5G-S57H: increases the rate of 12 ports from 1 Gbit/s to 5 Gbit/s.
L-1GUPG10G-S57H: increases the rate of 12 ports from 1 Gbit/s to 10 Gbit/s.
L-2.5GUPG5G-S57H: increases the rate of 12 ports from 2.5 Gbit/s to 5 Gbit/s.
L-2.5GUPG10G-S57H: increases the rate of 12 ports from 2.5 Gbit/s to 10 Gbit/s.
L-5GUPG10G-S57H: increases the rate of 12 ports from 5 Gbit/s to 10 Gbit/s.

Instructions:

After activating a license file, you need to run the assign group-speed [ slot slot-number ] group group-number speed command and restart the device to increase the rate of ports.
You can apply for multiple license control items to increase the rate of ports gradually. For example, to increase the rate of 12 ports on the S5732-H24UM2CC from 1 Gbit/s to 10 Gbit/s, you can apply for a single L-1GUPG10G-S57H control item, or apply for one L-1GUPG2.5G-S57H control item and one L-2.5GUPG10G-S57H control item.
Each of the following control items can be used to upgrade interfaces of different groups to different rates: L-1GUPG5G-S57H, L-1GUPG10G-S57H, and L-2.5GUPG10G-S57H. For example, with one L-1GUPG5G-S57H control item, you can run the assign group-speed [ slot slot-number ] group group-number speed command to upgrade the rate of one group of 12 interfaces from 1 Gbit/s to 2.5 Gbit/s and upgrade the rate of another group of 12 interfaces from 2.5 Gbit/s to 5 Gbit/s.
Each license control item takes effect on a group of 12 ports. As such, you need to purchase two license control items if you want to increase the rate of two groups of ports (that is, 24 ports). The rate of ports in each group is increased simultaneously, and two groups can have varying port rates. For example, you can increase the rate of one port group to 5 Gbit/s and that of another port group to 10 Gbit/s.
If the configuration of the assign group-speed [ slot slot-number ] group group-number speed command is different from that supported by control items in a license file, the following situations may occur:
- If license control items are insufficient, the rate of ports in groups with smaller group IDs is increased. For example, if the command is configured to increase the rate of two groups of ports to 10 Gbit/s but there is only one L-1GUPG10G-S57H control item in the license file, the rate of 12 ports in the group with a smaller group ID is increased to 10 Gbit/s.
- If the port rate configured in the command is less than that supported by a control item in a license control item, the port rate configured in the command takes effect. For example, if the command is configured to increase the rate of a group of ports to 5 Gbit/s but the control item in the license file is L-1GUPG10G-S57H, the rate of ports in the group is increased to 5 Gbit/s.
- If the port rate configured in the command is greater than that supported by the control item in a license control item, the port rate supported by the license control item takes effect. For example, if the command is configured to increase the rate of a group of ports to 10 Gbit/s but the control item in the license file is L-1GUPG5G-S57H, the rate of ports in the group is increased to 5 Gbit/s.

When multiple switches set up a stack, their license files and port rates are processed as described in Table 1.

**Table 1** License file and port rate processing for a stack
License on the Master Switch	Stack License and Port Rate	Example
There is no license file or the license file has expired.	The stack has no valid license file, and the standby and slave switches also have no valid license file. If the stack is set up for the first time, the upgraded port rates of the standby and slave switches still take effect. However, if the switches are restarted, their port rates restore to the default settings.	Before stacking: Switch 1 has no license file and its default port rate is 1 Gbit/s. The rate of ports on Switch 2 is increased to 5 Gbit/s by activating a license file. After stacking: If Switch 1 and Switch 2 set up a stack for the first time and are elected as the master and standby switches, respectively, the stack has no valid license file, and the port rate of Switch 2 is still 5 Gbit/s. After Switch 2 is restarted, its port rate restores to the default setting (1 Gbit/s).
A license file is available but it does not contain the ESNs of the standby and slave switches.	If the standby and slave switches have the same license control items as the master switch, the stack uses the license file of the master switch, and the three switches use their respective license files. The upgraded port rates will always take effect even when the switches are restarted or a master/standby switchover is performed. If not all license control items of the standby and slave switches are the same as those on the master switch, the stack uses the license file of the master switch, the standby and slave switches synchronize their license files with the license file of the master switch, and their port rates remain the same as those before the stack is set up (that is, the upgraded port rates still take effect). If the standby or slave switch is restarted, its port rate remains unchanged. If a master/standby switchover occurs in the stack, the license of the stack enters the trial state, which lasts for 60 days. Within the trial period, the port rates of switches remain unchanged. When the trial period expires, the port rates of the switches remain unchanged and will restore to the default setting only after the stack is restarted. Therefore, before the trial period expires, you are advised to apply for a new license file that contains the ESNs of all switches in the stack and load the new license file to the stack.	Before stacking: The port rates of Switch 1 and Switch 2 are increased to 10 Gbit/s and 5 Gbit/s respectively by activating license files. The license file of Switch 1 does not contain the ESN of Switch 2. After stacking: Switch 1 and Switch 2 are elected as the master and standby switches respectively. Therefore, the stack uses the license file of Switch 1, and Switch 2 synchronizes its license file with that of Switch 1. In this case, the port rate of Switch 2 remains 5 Gbit/s even after Switch 2 is restarted. If a master/standby switch occurs in the stack, the license file enters the trial state and the port rate of Switch 2 is still 5 Gbit/s within the 60-day trial period. When the trial period expires, the port rate remains 5 Gbit/s, and will restore to the default setting (1 Gbit/s) only after the stack is restarted.
A license file is available and it contains the ESNs of the standby and slave switches.	The stack uses the license file of the master switch, the standby and slave switches synchronize their license files with the license file of the master switch, and their port rates remain the same as those before the stack is set up. If the assign group-speed [ slot slot-number ] group group-number speed command is configured for the standby or slave switch and the switch is restarted, its port rate is increased to the new rate.	Before stacking: The port rates of Switch 1 and Switch 2 are increased to 10 Gbit/s and 5 Gbit/s respectively by activating license files. The license file of Switch 1 contains the ESN of Switch 2. After stacking: Switch 1 and Switch 2 are elected as the master and standby switches respectively. Therefore, the stack uses the license file of Switch 1, and Switch 2 synchronizes its license file with that of Switch 1. In this case, the port rate of Switch 2 remains 5 Gbit/s. If the assign group-speed [ slot slot-number ] group group-number speed command is configured for Switch 2 and Switch 2 is restarted, its port rate is increased to 10 Gbit/s.
