APX 1000™ Getting Started Guide
Configuring the Shelf Controller
Providing a basic system IP configuration
Assigning the Ethernet IP addresses
An APX 1000 unit creates an IP interface for each Ethernet port in the chassis. Use the Dir
command to list the IP interfaces, as follows:
admin> dir ip-interface
21 07/09/2001 16:08:59 { { any-shelf any-slot 0 } 0 }
33 07/23/2001 14:06:39 { { shelf-1 slot-4 1 } 0 }
21 07/09/2001 16:09:49 { { shelf-1 slot-4 2 } 0 }
21 07/09/2001 16:09:49 { { shelf-1 slot-4 3 } 0 }
21 07/09/2001 16:09:49 { { shelf-1 slot-4 4 } 0 }
21 07/09/2001 16:08:59 { { shelf-1 controller 1 } 0 }
The following commands assign to the shelf controller the address 1.1.1.1/24:
admin> read ip-interface { { shelf-1 controller 1 } 0 }
IP-INTERFACE/{ { shelf-1 controller 1 } 0 } read
admin> set ip-address = 1.1.1.1/24
admin> write
IP-INTERFACE/
{ { shelf-1 controller 1 } 0 }
written
Note:
By specifying an interface on the E-3ND egress card, the same commands can be used
to assign Ethernet addresses for carrying user traffic.
After you assign IP addresses, you can verify that the APX 1000 unit is a valid IP host on its
configured network by pinging other network hosts, as shown in the following example:
admin> ping 1.1.1.56
PING 1.1.1.56: 56 Data bytes
64 bytes from 1.1.1.56: icmp_seq=0 ttl=255 time=0 ms
64 bytes from 1.1.1.56: icmp_seq=3 ttl=255 time=0 ms
^C
--- 1.1.1.56: Ping statistics ---
2 packets transmitted, 2 packets received, 0% packet loss
round-trip min/avg/max = 0/0/0 ms
Configuring a default route
A default route is a static route that specifies a local destination for traffic bound for addresses
that are not on the local network and to which a known route does not exist. The default route
is generally the IP address of a local router that has more route information about how specific
destinations can be reached. When the default route is configured, the APX 1000 unit routes IP
packets with unknown destination addresses to the specified router. If no default route is
defined, the unit drops IP packets for which it has no route.
Figure 5-5 shows two APX 1000 units, each with an Ethernet egress interface on a subnet
connected to the same Ethernet segment as a local router. In this network, either APX 1000
unit can use the local router as its default route.
Note:
The Ethernet interface of the shelf controller is not intended to carry heavy traffic and
will generally be connected only to a local hub or switch for local administrative access.
