When do we really need to add a static route on the server?
Your server needs to have a valid route back to a client whenever you want communication to occur between the two devices.
Your servers and hosts have routing tables which tell them where to send packets that *they* create, just like gateway devices use routing tables to forward other devices' traffic (and also for traffic the gateways create themselves). A gateway could forward a packet just fine, but if your server does not have a valid route, your server will never send the packet to the gateway in the first place. Type "ip route" at the command line to see the kernel IP routing table.
The most common static route you'll have on a server or a client is the default route. A default route tells a host to send all packets that do not match any other routes to a particular destination. This saves you from setting static routes to every host or network you want your server to be able to reply to; it covers everything in one route table entry. To set a default route, you can use the command:
ip route add default dev <interface> via <next hop IP address>

Just want to know if someone has a clue about what could be happening here:
I have an AIX box with four NICs in Ether channel connected to a Cisco Switch.
When I try to ping the default gateway, sometimes it works, but sometimes it doesn't work unless it has a defined static route.

dump_sockdfr
DUMP_SOCKDFR(8) System Manager's Manual DUMP_SOCKDFR(8)
NAME
dump_sockdfr - Display contents of frozen route file for SOCKS server
SYNOPSIS
dump_sockdfr [infile]
DESCRIPTION
dump_sockdfr reads in a frozen route file for the SOCKS server and produces a listing of its contents on the standard output.
The argument is optional; if omitted, /etc/sockd.fr is assumed.
The frozen route file is produced by make_sockdfr and is essentially the memory image of the parsed route file. Using the frozen route file
can reduce the start-up delay of the SOCKS server program since it no longer has to parse the file contents.
When the SOCKS server starts, it always looks for the frozen route file /etc/sockd.fr first. If that file is not found, it then tries to
use the plain-text route file /etc/sockd.route. If you use frozen route file, you must remember to run make_sockdfr every time after you
modify the plain-text file or the SOCKS server will continue to use the frozen version of a previous route file.
FILES
/etc/sockd.fr, /etc/sockd.route
SEE ALSO
make_sockdfr(8), sockd.fr(5), sockd.route(5)
