Is this something that I need to check with our network team? We currently have 4 different subnets in our AIX lpars and they can talk to each other normally.
In principle: yes. In practice the overwhelming majority of switches/routers do this (at least this is my experience) per default. I just wanted to give the rationale behind having to state the default gateway for each NIM network.
Notice that "default gateway" here means the gateway used to access the client network: suppose you have a NIM-server with IP A out of network NetA and a client with the IP B out of network NetB. The NIM network you have to create will be NetB and its "default gateway" will be the router IP in NetB, not some interface on the NIM server. For example (suppose x.1 is always the router port for network x):
The gateway is NOT 10.1.1.1, which would be the standard gateway for the NIM server.

All,
I'm testing NIM on a 7026-m80 machine.

Hello All,
I believe my NIM master is fine. lsnim and cat /etc/niminfo gives me the right output. While doing "lsnim" on a client machine, I get ksh:lsnim:"not found".
Please someone be nice enough to explain what are the steps to verify the master and client connectivity to do all the NIM... (3 Replies)

Hi.
I change my client's IP and hostname but I forgot to change anything on the master. How can I redefine or modify my client's resource from my master, or with using smit niminit from my client ?

Iam attempting to add a client to NIM however the new client has a different subnet than master 10... & 193... , I've established from redbooks that it should be possible but can't find anything that states how?
Does anyone use nim in this way? (5 Replies)
hi Admins,
How can I check the NIM master hostname/IP name from NIM client ? I don't see any option that I can try with nimclient command.
Let me know..
Thanks, (5 Replies)
Hello, I have an AIX6.1 machine which is a nim client to my nim master which is also AIX6.1 machine.

netmasks
netmasks(4) File Formats netmasks(4)NAME
netmasks - network mask database
SYNOPSIS
/etc/inet/netmasks
/etc/netmasks
DESCRIPTION
The netmasks file contains network masks used to implement IP subnetting. It supports both standard subnetting as specified in RFC-950 and
variable length subnetting as specified in RFC-1519. When using standard subnetting there should be a single line for each network that is
subnetted in this file with the network number, any number of SPACE or TAB characters, and the network mask to use on that network. Network
numbers and masks may be specified in the conventional IP `.' (dot) notation (like IP host addresses, but with zeroes for the host part).
For example,
128.32.0.0 255.255.255.0
can be used to specify that the Class B network 128.32.0.0 should have eight bits of subnet field and eight bits of host field, in addition
to the standard sixteen bits in the network field.
When using variable length subnetting, the format is identical. However, there should be a line for each subnet with the first field being
the subnet and the second field being the netmask that applies to that subnet. The users of the database, such as ifconfig(1M), perform a
lookup to find the longest possible matching mask. It is possible to combine the RFC-950 and RFC-1519 form of subnet masks in the net-
masks file. For example,
128.32.0.0 255.255.255.0
128.32.27.0 255.255.255.240
128.32.27.16 255.255.255.240
128.32.27.32 255.255.255.240
128.32.27.48 255.255.255.240
128.32.27.64 255.255.255.240
128.32.27.80 255.255.255.240
128.32.27.96 255.255.255.240
128.32.27.112 255.255.255.240
128.32.27.128 255.255.255.240
128.32.27.144 255.255.255.240
128.32.27.160 255.255.255.240
128.32.27.176 255.255.255.240
128.32.27.192 255.255.255.240
128.32.27.208 255.255.255.240
128.32.27.224 255.255.255.240
128.32.27.240 255.255.255.240
128.32.64.0 255.255.255.192
can be used to specify different netmasks in different parts of the 128.32.0.0 Class B network number. Addresses 128.32.27.0 through
128.32.27.255 have a subnet mask with 28 bits in the combined network and subnet fields (often referred to as the subnet field) and 4 bits
in the host field. Furthermore, addresses 128.32.64.0 through 128.32.64.63 have a 26 bits in the subnet field. Finally, all other
addresses in the range 128.32.0.0 through 128.32.255.255 have a 24 bit subnet field.
Invalid entries are ignored.
