Ethernet interface configuration

Ziggy Filek — Wed, 20 Dec 2006 17:43:58 GMT

I have 4 NICs on an ES80. One is configured as WE0. $TCPIP SHOW INTERFACE just shows this one:
TCPIP> show interface we
Packets
Interface IP_Addr Network mask Receive Send MTU

WE0 10.171.2.7 255.255.255.0 299903 345728 1500
TCPIP>

How do I configure another one to be used as failSAFE IP? Do I need to plug it into network first?
When I use the approach as described in the Chapter 5 of the TCPIP Services for OpenVMS Management nothing seems to work as advertised.
When I go
TCPIP> set interface WE1 /HOST=10.171.2.7
the show interface command and the "show interface we" give different outputs:
TCPIP> show interface
Packets
Interface IP_Addr Network mask Receive Send MTU

LO0 127.0.0.1 255.0.0.0 96198 96198 4096
WE0 10.171.2.7 255.255.255.0 300603 346593 1500
WE1 0 0 1500
TCPIP> show interface we
Packets
Interface IP_Addr Network mask Receive Send MTU

WE0 10.171.2.7 255.255.255.0 300637 346617 1500
TCPIP>
I'd appreciate step-by-step instructions, if possible, since I already read the manual, to no avail.

Thanks!

better,you run sys$manager:tcpip$config.com and and then go to core components interface option.You have four interface WE0,WE1,WE2,WE3. After configuring WE0 interface it prompts for failSafe ip and enter the interface you want to configure as failSAFE for eg. WE1 ,then you can also configure WE2 interfce and WE3 as its failSAFE IP .
For example if u configure we1 as failsafe ip of we0 and we3 as failsafe ip of we2 it looks liks as follows...
TCPIP>show int
Interface IP_addr Network Mask Receive send MTU
we0 10.192.0.23 255.255.0.0 123426 89756 1500
we1 0 0 1500
we2 10.192.1.23 255.255.255.0 35678 87547 1500
we3 0 0 1500

Ziggy,

when playing around with interface alias entries and failSAFE IP, it's more convenient to use the ifconfig commands:

$ @SYS$MANAGER:TCPIP$DEFINE_COMMANDS

$ ifconfig -a ! show interfaces

$ ifconfig ie0 alias 10.20.30.205 netmask 255.255.255.0

$ ifconfig ie0 -alias 10.20.30.205

Thank you guys: I'm closing this thread since I want to open a new one with more specific description of the problem.
