maximum number of ip addresses per interface

[gunhp]

Hi,

What is the maximum number of ip addresses that can be assigined to single interface ( for example by lan0:1...lan0:N) ?

i'm not sure of this but i thought one interface may have only one internet address. the gated.conf(3) man page may have more information.

i meant the gated.conf(4) man page .

Stoled from:

http://docs.hp.com/cgi-bin/fsearch/...network|card|multiple&queryid=20040204-101623

IP addresses are configured only on each primary network interface card; standby cards are not configured with an IP address. Multiple IP addresses on the same network card must belong to the same IP subnet.

In addition to the stationary IP address, you normally assign one or more unique IP addresses to each package. The package IP address is assigned to the primary LAN interface card by the cmmodnet command in the package control script when the package starts up. The IP addresses associated with a package are called relocatable IP addresses (also known as package IP addresses or floating IP addresses) because the addresses can actually move from one cluster node to another. You can use up to 200 relocatable IP addresses in a cluster spread over as many as 30 packages.

Hope this helps.

It's 8192 virtual IPs for an interface.
ndd -get /dev/ip ip_addrs_per_if show 255.
ndd -set /dev/ip ip_addrs_per_if 8192 OK.
ndd -set /dev/ip ip_addrs_per_if 8193 Failed.
