dedicated mode on Nexus7000

Hi,

i like to configure two ports in dedicated mode (eth4/1 + eth4/2).

the ports are on a modultype "N7K-F132XP-15" (32x10GE)

all ports are in one vdc membership (default configuration)

ive tried this for port eth 4/1:

bciscon7k01(config)# int eth 4/1,eth 4/3,eth 4/5,eth 4/7

bciscon7k01(config-if-range)# shut

bciscon7k01(config-if-range)# int eth 4/1

bciscon7k01(config-if)# rate-mode dedicated

after that i get the following message:

"Ignoring command for interface Ethernet4/1 as rate-mode is fixed."

i didnt find any documentation to this error message.

whats wrong in my configuration?

Rate Mode

On a 32-port 10-Gigabit Ethernet module, each set of four ports can handle 10 gigabits per second (Gb/s) of bandwidth. You can use the rate-mode parameter to dedicate that bandwidth to the first port in the set of four ports or share the bandwidth across all four ports.

Table 2-1 identifies the ports that are grouped together to share each 10 Gb/s of bandwidth and which port in the group can be dedicated to utilize the entire bandwidth.

Note All ports in each port group must be part of the same virtual device context (VDC). For more information on VDCs, see the Cisco Nexus 7000 Series NX-OS Virtual Device Context Configuration Guide, Release 5.x.


I found this link from Cisco doc.

Greetings Andreas,

N7K-F132XP-15 doesn't have a concept of dedicated/shared mode ports as there is no port-ASIC level oversubscription. dedicated/shared config is for use on "M1" class of modules. [1]

HTH,

/Phil
