Connecting three B7800

I have to connect three B7800, one for each site, using FCIP.

Can I use two GbE ports together (only 1 tunnel) to connect each B7800 with the other two B7800 ?

Thanks in advance.

Example:

Configuring a GbE port IP address

SiteA_7800 > portcfg ipif ge0 create 192.168.0.1 255.255.255.0 1500

SiteA_7800 > portcfg ipif ge1 create 192.168.1.1 255.255.255.0 1500

SiteB_7800 > portcfg ipif ge0 create 192.168.0.2 255.255.255.0 1500

SiteB_7800 > portcfg ipif ge1 create 192.168.1.2 255.255.255.0 1500

SiteC_7800 > portcfg ipif ge0 create 192.168.0.3 255.255.255.0 1500

SiteC_7800 > portcfg ipif ge1 create 192.168.1.3 255.255.255.0 1500

Creating an FCIP tunnel

SiteA_7800 > portcfg fciptunnel 16 create -c 1

SiteB_7800 > portcfg fciptunnel 16 create -c 1

SiteC_7800 > portcfg fciptunnel 16 create -c 1

Add circuits

SiteA_7800 > portcfg fcipcircuit 16 create 0 192.168.0.2 192.168.0.1 -b 1000000 –B 1000000

SiteA_7800 > portcfg fcipcircuit 16 create 1 192.168.0.3 192.168.0.1 -b 1000000 –B 1000000

SiteA_7800 > portcfg fcipcircuit 16 create 1 192.168.1.2 192.168.1.1 -b 1000000 –B 1000000

SiteA_7800 > portcfg fcipcircuit 16 create 1 192.168.1.3 192.168.1.1 -b 1000000 –B 1000000

SiteB_7800 > portcfg fcipcircuit 16 create 0 192.168.0.1 192.168.0.2 -b 1000000 –B 1000000

SiteB_7800 > portcfg fcipcircuit 16 create 1 192.168.0.3 192.168.0.2 -b 1000000 –B 1000000

SiteB_7800 > portcfg fcipcircuit 16 create 1 192.168.1.1 192.168.1.2 -b 1000000 –B 1000000

SiteB_7800 > portcfg fcipcircuit 16 create 1 192.168.1.3 192.168.1.2 -b 1000000 –B 1000000

SiteC_7800 > portcfg fcipcircuit 16 create 0 192.168.0.1 192.168.0.3 -b 1000000 –B 1000000

SiteC_7800 > portcfg fcipcircuit 16 create 1 192.168.0.2 192.168.0.3 -b 1000000 –B 1000000

SiteC_7800 > portcfg fcipcircuit 16 create 1 192.168.1.1 192.168.1.3 -b 1000000 –B 1000000

SiteC_7800 > portcfg fcipcircuit 16 create 1 192.168.1.2 192.168.1.3 -b 1000000 –B 1000000

Re: Connecting three B7800

Hi,

You cannot perform the config in the example because an FCIP tunnel can only connect two switchs.

You should create 3 tunnels to perform a full mesh topology instead, and each tunnel can contain two circuits.

Thanks felipon, do you mean something like this ?

Re: Connecting three B7800

to be honestly, I'm not sure what you meaning with:

-->>Can I use two GbE ports together (only 1 tunnel) to connect each B7800 with the other two B7800 ?

however, see attached FCIP Theory

Re: Connecting three B7800

Hi MaximF,

the creating GBE IP Addresses looks good.

When you are creating the FCIP Tunnel, the first circuit is automatically build.

So correct ist:

SiteA_7800 > portcfg fciptunnel 16 create 192.168.0.2 192.168.0.1 -b 300000 –B 1000000

SiteB_7800 > portcfg fciptunnel 16 create 192.168.0.1 192.168.0.2 -b 300000 –B 1000000

After that you add circuits to the tunnel:

SiteA_7800 > portcfg fcipcircuit 16 create 1 192.168.1.2 192.168.1.1 -b 300000 –B 1000000

SiteB_7800 > portcfg fcipcircuit 16 create 1 192.168.1.1 192.168.1.2 -b 300000 –B 1000000

So as you see i changed the min. committed rate to 1/3 Gig. Because you are using 3 connections it woul be better to hav min. commited rate set to 1/3 Gig and the max. to 1 Gig.
