chsystemethernet
The chsystemethernet command is used to set the priority tag for host attachment, system, and storage traffic.
Syntax
Parameters
- -hostattachcos host_attach_priority_tag
- (Optional) Specify the system-wide host attach priority tag that you want to be used by all host attach traffic over iSCSI, iSER, or NVMeF. The value must be in the range 0 (default) - 7.
- -systemcos priority_tag_for_system_traffic
- (Optional) Specify the system-wide clustering priority tag that you want to be used by system traffic. The value must be in the range 0 (default) - 7.
- -storagecos storage_priority_tag
- (Optional) Specify the system-wide storage priority tag that you want to be used by storage traffic. The value must be in the range 0 (default) - 7.
Description
Use the chsystemethernet command to set system-wide Ethernet related properties. This command affects all existing and new iSCSI sessions. The priority of iSCSI packets changes immediately after the priority tag is changed by using the chsystemethernet command. Existing iSER sessions continue to use the old priority tag values. To change the priority tag value for an iSER session, the command must be used before any connections are established or you must close and reestablish all the connections after you run the command so the priority tag values take effect.
An invocation example to set the host attach priority tag (class of service) to 4, system priority tag to 5, and storage priority tag to 6.
