Figure 23. Static Pinning with Four Fabric Links
Ports can be divided as follows:
●
pinning max-links 1: All 48 host ports use one fabric port only (and this the first port connected between
the Cisco Nexus 5000 Series Switch and the Cisco Nexus 2000 Series Fabric Extender). This assignment is
represented by configuration A in Figure 23.
●
pinning max-links 2: The 48 ports are divided into two groups. The first 24 ports use fabric link 1, shown
as a dotted line in Figure 23, and the remaining 24 ports use fabric link 2, shown as a solid line. This
assignment is represented by configuration B in Figure 23.
●
pinning max-links 3: The 48 ports are divided into three groups. The first 16 ports use fabric link 1, the
second 16 ports use fabric link 2, and the remaining ports use fabric link 3. This assignment is represented
by configuration C in Figure 23.
●
pinning max-links 4: The 48 ports are divided into four groups. The first 6 ports use fabric link 1, the
second 6 ports use fabric link 2, the following 6 ports use fabric link 3, and the remaining 6 ports use fabric
link 4. This assignment is represented by configuration D in Figure 23.
The pinning order depends on the order of fabric port configuration, regardless of when the ports come up or
whether they come up.
To verify the way that physical interfaces on the Cisco Nexus 2000 Series module are assigned to the fabric ports,
you can use this command:
show fex <number> details
The following example shows the result of a pinning configuration consisting of three pinning maximum links, with
only two fabric links:
tc-nexus5k01# show fex 100 deta
