Without portfast it will take 50 seconds for the port to transition to 
forwarding. Your delay will need to be longer than that.

You did not mention which rhel version you are using but interfaces on dells in 
rhel 6.1 will show up as em1, em2, etc. by default instead of eth0, eth1. Both 
dell and redhat mention it in their docs.

Personally I would add one line per port on the switches ;-)

Try enabling portfast (rstp edge) the ports on your Cisco switch? It'll 
transition the port to forwarding directly without going through blocking, 
listening or learning state.

Hi,

I am using a Poweredge R710 with 4 embedded NICs.  I have a kickstart procedure 
using  http. So i boot from my USB, type in:
linux ks=http://x.x.x.x./path/ks.cfg

Anaconda prompts me then which eth to use, i selected eth0 (which is connected 
to the network). But the sending request for IP information is taking forever. 
I them timesout, asks to select  ipv4/ipv6 options.  And back to "sending 
request for ip info...."  I am also using a cisco switch on the other end and 
changes in the switch config is not an option.This issue defeats auto install 
of Redhat. IF i connect the server into a normal switch (not Cisco), kickstart 
works fine.,

How to set something that anaconda will continue to request & wait for DHCP ip.

thanks,
sirjun
