A network service alias is a set of configurations that consist of protocol and port mappings. Both source and destination ports are configurable. For each protocol, up to two source port ranges and up to two destination port ranges can be configured. A maximum of four protocol entries can be configured per network service alias.
Use a service alias to associate more than one IP address to a network interface, providing multiple connections to a network from a single IP node.
To define a service alias configuration for a RF Domain:
Protocol | Specify the protocol for which the alias has to be created. Use the drop down to select the protocol from eigrp, gre, icmp, igmp, ip, vrrp, igp, ospf, tcp, and udp. Select other if the protocol is not listed. When a protocol is selected, its protocol number is automatically selected. |
Source Port (Low and High) | This field is relevant only if the protocol
is either tcp or udp. Specify the source ports for this protocol entry. A range of ports can be specified. Select the Enter Ranges button next to the field to enter a lower and higher port range value. Up to eight (8) such ranges can be specified. |
Destination Port (Low and High) | This field is relevant only if the protocol
is either tcp or udp. Specify the destination ports for this protocol entry. A range of ports can be specified. Select the Enter Ranges button next to the field to enter a lower and higher port range value. Up to eight (8) such ranges can be specified. |
