Software ports
The appliance has several software ports. The customer’s network administrator must modify
the local name–to–port–number tables to include the port names and numbers listed in Table 2.
The network administrator must have these names to open the ports in the firewall and allow
IP mirror traffic to flow through the network. The network administrator should refer to the
firewall documentation to determine how to open these ports for external access. To allow
external access to the appliance user interface, the network administrator should open TCP
port 80 in the firewall.
Table 2 lists the software port information.
