how to add a switch to an existing fabric
Hello,
I have only done this task one time before so I am a little rusty. I need to add a switch into an existing fabric, actually one in each fabric A and B. I will configure the switches, then assign it a domain id greater than the core switch.
I don't remember what to do after that, and I can't seem to find the answer in the DCNM manual. Any feedback is greatly appreciated.

ok, so let's assume that you will use port-channel 13 for this brand new switch. Say on switch 9509 port-channel will consists of ports 1/2, 2/2, 3/2 and 4/2 (ports on different blades for redundancy). On switch 9148 we will use ports 1/1, 1/4, 1/7 and 1/10
On 9509 (A Fabric)
interface port-channel 13
channel mode active
switchport trunk mode on
switchport trunk allowed vsan 100
int fc1/2
channel-group 13 force
no shut
int fc2/2
channel-group 13 force
no shut
int fc3/2
channel-group 13 force
no shut
int fc4/2
channel-group 13 force
no shut
On 9148 (A Fabric)
interface port-channel 13 ( i am using the same port channel as on 9509, that's what i do in my environemt so i know exactly the matching port-channel on the other switch. It's up to you, it does not have to be the same port-channel number)
channel mode active
switchport trunk mode on
switchport trunk allowed vsan 100
int fc1/1
channel-group 13 force
no shut
int fc1/4
channel-group 13 force
no shut
int fc1/7
channel-group 13 force
no shut
int fc1/10
channel-group 13 force
no shut
So after you complete the initical config and configure this port-channel ..you can go ahead and connect the cables between the switches. The ports should become green in device manager, and port type should be TE.
You live in Chicago right ?

Thank you Dynamox, yes, so far so good. I configured the switch for VSAN 100. Now I want to set the fcdomain. I have attached my current fabric switches fcdomains for reference.

fcdomain domain 83 static vsan 100
fcdomain fcid persistent vsan 100
fcdomain restart vsan 100
make sure to do this before you connect the new switch to the fabric.

One quick question,
I am trying to set the fcdomain id to 0x53(83) but getting a syntax error.
My two previous switches were 0x52(82), 0x51(81).
Not sure why I am getting this error. My apologies for being forgetful about this.

i personally prefer to do major fabric changes like that off hours. I mean there is really not much for you to do, if you have done all your pre-work ahead of time then it should be non-eventful.
Keep the questions coming, i am glad to help where i can. My offer still stands if you need my assistance over Teamviewer (sorry don't have access to Webex).
