Configuring IPX
USING THE CLI
To increase the hop count increment assessed to interface 5, enter the following commands:
NetIron(config)# int e 5
NetIron(config-if-5)# ipx-rip-update-hop-count-increment 10
NetIron(config-if-5)# ipx-sap-update-hop-count-increment 10
Syntax: ipx-rip-update-hop-count-increment <2-15>, ipx-sap-update-hop-count-increment <2-15>
USING THE WEB MANAGEMENT INTERFACE
You cannot modify hop count increments using the Web management interface.
Modify the RIP Advertisement Packet Size
The default IPX RIP packet size is 432 bytes, which allows 50 routes plus 32 bytes of header in an IPX RIP update
packet. Each route requires eight bytes. You can configure the packet size to be from 40 bytes (enough for one
route) – 1488 bytes (enough for 182 routes).
NOTE: You can specify packet length that does not fall evenly on a route or server boundary. The device will
use the packet size but will include only the number of routes or servers that fit entirely within the packet.
To change the RIP advertisement packet size, use the following CLI method.
USING THE CLI
EXAMPLE:
To change the maximum packet size of IPX RIP advertisements sent on interface 1/1 from the default 432 bytes to
832 bytes, enter the following command. This command increases the number of IPX RIP routes an
advertisement packet holds from 50 to 100.
BigIron(config) int e 1/1
BigIron(config-if-1/1) ipx rip-max-packetsize 832
BigIron(config-if-1/1) write memory
Syntax: ipx rip-max-packetsize <bytes>
The number of bytes can be from 40 bytes (enough for one route) – 1488 bytes (enough for 182 routes). The
default is 432 bytes.
USING THE WEB MANAGEMENT INTERFACE
You cannot modify the RIP advertisement packet size using the Web management interface.
Modify the SAP Advertisement Packet Size
The default IPX SAP packet size is 480 bytes, which allows seven servers plus 32 bytes of header in an IPX SAP
update packet. Each server requires 64 bytes. You can configure the packet size to be from 96 bytes (enough for
one server) – 1440 bytes (enough for 22 servers).
NOTE: You can specify packet length that does not fall evenly on a route or server boundary. The device will
use the packet size but will include only the number of routes or servers that fit entirely within the packet.
To change the SAP advertisement packet size, use the following CLI method.
USING THE CLI
EXAMPLE:
To change the maximum number of bytes in IPX SAP advertisements sent on interface 5/1 from 480 to 672
(enough for 10 servers plus the 32 bytes of packet header), enter the following commands:
BigIron(config) int e 5/1
BigIron(config-if-5/1) ipx sap-max-packetsize 672
BigIron(config-if-5/1) write memory
