Zoning Configuration of Cisco Nexus 5000 Switches

 SAN-Zoning Configuration using Cisco NEXUS 5k Switch

for example pwwn # is 10:00:00:00:c9:62:82:36

fcid 0x01002e  get the id from show flogi database

fcalis name is sql02_hba2_p0
zonename ql02_hba2_p0_VMAX_4634_10E0
vsan database# 212

vsan 212 wwn 10:00:00:00:c9:62:82:36 fcid 0x01002d dynamic
fcalias name sql02_hba2_p0 vsan 212
    member pwwn 10:00:00:00:c9:62:82:76

zone name sql02_hba2_p0_VMAX_4634_10E0 vsan 212
   
    member fcalias vmbkp02_hba2_p0

zone name sqlp02_hba2_p0_TLB01_TAPE2 vsan 212
   
    member fcalias sqlp02_hba2_p0
zoneset name Zoneset_B_01242012 vsan 212


The procedure is

• create zone
• add members to zone
• create zoneset
• add multiple zones to a zoneset
• activate the zone set
• save the config

conf t

switch(config)# zone name sql02_hba2_p0_VMAX_4634_10E0 vsan 212
sswitch(config-zone)# member pwwn 10:00:00:00:c9:62:82:36
 switch(config-zone)# member fcid 0x01002e

(fcalias can be called accounting for easy undestanding)
switch(config-zone)# member fcalias sql02_hba2_p0

create ZONE set

conf t

switch(config)# zoneset name Zoneset_B_01242012 vsan 212
witch(config-zoneset)# member sql02_hba2_p0_VMAX_4634_10E0

(If the specified zone name was not previously configured,
 this command will return the Zone not present error message)


switch(config-zoneset)# zone name sqlp02_hba2_p0_TLB01_TAPE2 


Activate a Zone set

switch(config)# zoneset activate name zoneset_B_01242012 vsan 212



DISPLAY ZONE CONFIG


show zone vsan 212
show zoneset vsan 212
show zone member pwwn #
show zone active
 show zone status

it is better to have single Zoneset and several zones assigned to it.

NEXUS 5K FEX CHEAT SHEET

Nexus Switches-Nexus Cheat Sheet

Nexus is one of the dominant switches in data centers, most companies already rolled out Nexus Switches like 7k,5k and Fabric Extender 2k. Nexus 1k series is for low latency applications.

The following commands are normally used for Configuring/monitoring Nexus Switches.

Feature- add a feature in switch   feature ssh

Interface

Interface designation   - int eth slot#/port#

Channel-group # mode active/passive

Int po# ( port-channel)

Example

Channel-group 10 mode active
Int portchannel10
Switchport mode access

CAM table

To find the port of a host using mac address

show mac-address-table address [mac address]

FCOE

Enable fcoe mode

Int x/y

Fcoe mode on/auto

VFC

Interface vfc10

Bind interface e1/10

QOS For FCOE

Class-map class-fcoe

Match cos #

ZONING

VSAN- Virtual Storage Network

Zone name name vasn #

Member pwwn#,fcalias

Zoneset name

To activate

Zoneset activate name [zonename] vsan #

Example

int fc1/24

vsan database

vsan 102 interface fc1/24

vsan 202 wwn 10:00:00:00:c9:62:ab:a7 fcid 0x010027 dynamic

fcalias name SQL31_hba1_p0 vsan 102  

fcalias name SQL31_hba1_p0 vsan 102

    member pwwn 10:00:00:00:c9:62:ab:a7

zone name disql31_hba1_p0_4634_10f0 vsan 102

zoneset name Zoneset_B_01242012 vsan 102

zone sql31_hba1_p0_4634_10f0 to zoneset Zoneset_B_01242012 on VSAN 102

zoneset activate name Zoneset_B_01242012 vsan 102

FEX 

For example 2148T has 48x 1ge server ports and 4x10GE uplinks

It is managed by 5k or 7k

There is not PORT CHANNEL config from FEX to server ports

It appears as a line card of Nexus 5k

FEX config managed by 5k and local memory storage for the config

FEX is discovered by SDP protocol

Define number of uplinks

Conf t

Fex 100

Pinning max-links 4

Attach a FEX to interface

Conf t

Int e3/1

Switchport mode fex-fabric

fex associate 100

exit

verify FEX

show fex 100

or show fex 100 detail

other commands are

show inventory fex 100

show version fex 100

show environment fex 100

show diagnostic result fex 100

show logging onboard fex 100

reload fex 100

show tech-support fex 100
