gh utilization, though. Devices such as backup servers that pull in a lot of traffic from multiple sources are one example. Database servers are another. If your network is large, you may need to dedicate your uplink ports SO that you can best utilize the avail- able speed of your links. To configure a port in dedicated mode, use the rate-mode interface command. The options are dedicated and shared: Chapter 18: Cisco Nexus NX-7K-1-Cozy(config-if)# rate-mode ? dedicated Rate mode is dedicated shared Rate mode is shared When you're setting a port to dedicated mode, all of the ports in the port group must be in the admin-down state or you will get the following error: NX-7K-1-Cozy(config-if)# rate-mode dedicated ERROR: Ethernet7/1: all ports in the port-group must be in admin shut state Here, I'll shut down all the ports in the first port group on module 7, then dedicate the ASIC to the first port: NX-7K-1-Cozy(config-if)# int e7/1-4 NX-7K-1-Cozy(config-if-range shut NX-7K-1-Cozy(config-if-range)# int e7/1 NX-7K-1-Cozy(config-if)# rate-mode dedicated The switch now prevents me from bringing up the other ports in the port group: NX-7K-1-Cozy(config-if)# int e7/3 NX-7K-1-Cozy(config-if)# no shut ERROR: Ethernet7/3: Config not allowed, as first port in the port-grp is dedicated The port will now have a dedicated (D) flag in the output of show int brief: NX-7K-1-Cozy(config-if-range)# sho int brie I beg Eth7 Ethernet Type Mode Status Reason Speed Interface Eth7/1 eth routed up 10G(D) -- Eth7/2 eth routed up 10G(S) -- Eth7/3 eth routed down SFP not inserted auto(S) -- Eth7/4 routed down SFP not inserted auto(S) - [--output truncated- ] The interface will report that it is in dedicated rate mode: X-7K-1-Cozy# sho int e7/1 Ethernet7/1 is up Hardware: 10000 Ethernet, address: 0026.9807.95c2 (bia 5475.d09a.81dc) MTU 1500 bytes, BW 10000000 Kbit, DLY 10 usec, reliability 255/255, txload 1/255, rxload 1/255 Encapsulation ARPA full-duplex, 10 Gb/s, media type is 10g Beacon is turned off Auto-Negotiation is turned off Input flow
