OSPF Reference Bandwidth in NX-OS (4.1(5))

To control how Open Shortest Path First (OSPF) calculates default metrics for an interface, use the auto-cost command. To assign the default reference bandwidth of 40Gb/s, use the no form of this command.

auto-cost reference-bandwidth bandwidth [Gbps | Mbps]

Defaults

40 Gb/s. The bandwidth defaults to Gb/s if you do not specify the Gpbs or Mbps keyword.

I wonder why Cisco is leaning towards 40G instead of 100G.
One would think that Cisco will sell 40G linecards to the customer and .... a few months later the same customer has to buy 100G linecards.

14th is a sweet number

Congratulations Roger. You are the best .. of all time !!!


Roger and Andre

I think Roger will regain No.1 ranking before the end of the year.

Nexus 7000 Notes - 4 (from test lab)

"write mem" (or any write command for that matter) is gone.

"copy run star" take approx 15 seconds to write the config and idle for another 35 seconds (exactly) before returning to the command. (have to figure out what is going on during that time)

Nexus no longer supports PagP. It is either LACP or EtherChannel.

OSPF process can either be a number or a name i.e. supports alpha-numeric OSPF process ID. OSPF network statements are now configured per interface basis instead of in router configuration. Not sure if it a good thing since OSPF network statements are scattered all over the places.

"show process cpu history" is gone.
"show process cpu" shows unfamiliar processes (looks like link processes). My co-worker says Cisco fixed high CPU problem by not showing the numbers to the users - at least with a familiar command.
