Switch 300 and ISL

Hi,

 

my questions about ISL trunk:

 

It can be created ISL trunk via a single cable?

 

Is this output fabricshow ISL trunk?

 

Switch ID Worldwide Name Enet IP Addr FC IP Addr Name
-------------------------------------------------------------------------
11: fffc0b 10:00:50:eb:1a:79:9c:3b 172.16.178.26 0.0.0.0 "NMSK0055"
12: fffc0c 10:00:00:05:1e:81:7b:16 0.0.0.0 0.0.0.0 >"NMSK0056"

 

What commands used to diagnose, the ISL work?

 

Thank you

Re: Switch 300 and ISL

Yes you can form an ISL with one port, but two is recommended for redundancy.

What is the output from switchshow, fabricshow, islshow?

You should be running the latest fos.

Re: Switch 300 and ISL

Hi Radek,

 

                  Single ISL link can not act as ISL Trunk.

Trunking Brief :

 

The trunking feature optimizes the use of bandwidth by allowing a group of links to merge into a
single logical link, called a trunk group. Traffic is distributed dynamically and in order over this trunk
group, achieving greater performance with fewer links. Within the trunk group, multiple physical
ports appear as a single port, thus simplifying management. Trunking also improves system
reliability by maintaining in-order delivery of data and avoiding I/O retries if one link within the trunk
group fails.

 

The following requirements apply to all types of trunking:
• The Trunking license must be installed on every switch that participates in trunking.
• All of the ports in a trunk group must belong to the same port group.
• All of the ports in a trunk group must be running at the same speed.
• All of the ports in a trunk group must be configured for the same distance.
• All of the ports in a trunk group must have the same encryption, compression, QoS, and FEC
settings.
• Trunk groups must be between Brocade switches (or Brocade adapters, in the case of F_Port
trunking). Brocade trunking is proprietary and not supported on M-EOS or third-party switches.

• There must be a direct connection between participating switches.
• Trunking cannot be done if ports are in ISL R_RDY mode. (You can disable this mode using the
portCfgIslMode command.)
• Trunking is supported only on FC ports. Virtual FC ports (VE_ or VEX_Ports) do not support
trunking.
