MODULI   M1- F1 - F2

M1

N7K-M132XP-12 (4 interfaces x 8 port groups = 32 interfaces)—Interfaces belonging to the same port group must belong to the same VDC. See the example for this module in Figure 5-1.

• N7K-M132XP-12L (same as non-L M132) (1 interface x 8 port groups = 8 interfaces)—All M132 cards require allocation in groups of 4 ports and you can configure 8 port groups.

Table 5-1 shows the port numbering for the port groups.

On the Cisco Nexus 7000 Series 32-port, 10-Gbps Ethernet module N7K-F132XP-15, you must allocate the interfaces on your physical device in the specified combination. This module has 16 port groups that consist of 2 ports each (2 interfaces x 16 port groups = 32 interfaces). Interfaces belonging to the same port group must belong to the same VDC (see Figure 5-2).

Note You can configure the limit-resource module-type command only from the VDC configuration mode and not from a VDC resource template.

On the Cisco Nexus 7000 Series 48-port, 10-Gbps Ethernet module N7K-F248XP-25, you must allocate the interfaces on your physical device in the specified combination. This module has 12 port groups that consist of 4 ports each (4 interfaces x 12 port groups = 48 interfaces). Interfaces belonging to the same port group must belong to the same VDC (see Figure 5-3).

Note When you add or delete interfaces, the Cisco NX-OS software removes the configuration and disables the interfaces.

---

When interfaces in different VDCs share the same port ASIC, reloading the VDC (with the reload vdc command) or provisioning interfaces to the VDC (with the allocate interface command) might cause short traffic disruptions (of 1 to 2 seconds) for these interfaces. If such behavior is undesirable, make sure to allocate all interfaces on the same port ASIC to the same VDC.

 

To see how the interfaces are mapping to the port ASIC, use this command:

The interface number is listed in the FP port column, and the port ASIC number is listed in the MAC_0 column, which means that in the above example, interfaces 1 through 12 share the same port ASIC (0).
