Configuring the HRE-X Router Port

Various services in the switch use the HRE-X router port MAC registers. The registers are allo-
cated as the services are loaded at startup. The hrex submenu contains five commands for use
with the Hardware Routing Engines (HREs). The hrexassign command allows you to config-
ure the switch so that registers are reserved for particular services. The hrexdisplay command
allows you to view your current configuration. To display the hrex submenu, enter
hrex
at the system prompt. A screen similar to the following is displayed.
