Lancrad - APA issue

[G V R Shankar]

Hello All,

I have two systems, say A and B, running on HP-UX 11.23. Both are rx7620. I have configured APA on both the systems. lan0 and lan5 are both inbuilt cards.
HP A6794-60001 PCI 1000Base-T

Due to some IOS upgarde on router end, the lan speed on my servers got changed. Both of them became 100 HD Auto On.

When I issued the following command on system A, the lan speed changed to 100 FD Auto off

lanadmin -X 100FD auto_off 0
lanadmin -X 100FD auto_off 5

But, when I issued the same commands on system B, it gave the following error.

ERROR:could not process request

I had to stop APA and issue the lanadmin command to make it 100 FD Auto On.

On both A and B the following o/p is same.

$ swlist -l patch |grep -i Aggregation
# HP-APA-FMT B.11.23.05 HP Auto-Port Aggregation APA formatter product.
# HP-APA-KRN B.11.23.05 HP Auto-Port Aggregation APA kernel products.
# HP-APA-KRN.APA-KRN B.11.23.05 HP Auto-Port Aggregation APA kernel library
# HP-APA-LM B.11.23.05 HP Auto-Port Aggregation LM commands.
# HP-APA-RUN B.11.23.05 HP Auto-Port Aggregation APA command products.
# HP-APA-RUN.APA-RUN B.11.23.05 HP Auto-Port Aggregation APA command libraries
# HP-APA-SAM B.11.23.05 HP Auto-Port Aggregation APA SAM product.

Could any one please guide me how and why this has happened?

Regards,
Ravi.

Shalom ravi,

APA or no APA those NIC cards must be run auto-negotiate to function correctly.

It is not a correct response to an IOS router problem for you to bring your systems to their knees.

Put the systems back to auto-negotiate with lanadmin and have your network group put the routers into 1000 Base T full duplex, permitting auto negotiation.

Its not an APA problem. A good rule in IT is when the last thing you did breaks something, fix that last thing you did.

I of course could be wrong and there may be some patch related to your particular Cisco router, but I doubt it in this case.

Installed the patch PHNE_36403. Every thing looks fine.
