Cisco UCS 6100 Series Configuration Limits for Cisco UCS Manager, Release 1.4

This document describes the Cisco configuration limits for Cisco UCS 6100 Series fabric interconnects running Cisco UCS Manager, release 1.4.

Configuration Limits

The following table lists the Cisco verified limits for Cisco UCS 6100 series fabric interconnects running Cisco UCS Manager, release 1.4.

Table 1 Ethernet Environments

Feature

Cisco UCS 6100 Series

Active VLANs per system

1024

Note   

32 VLANS are set aside for VSANs and the remaining are the VLANs.

VLAN/VSAN ID space per system

4013 unreserved space

STP logical Interfaces (also referred to as VLAN port count) per fabric interconnect

Note    The only exception is for failover vNICs. These consume resources on a per UCS system basis.

6000

VIFs (virtual interfaces on the fabric interconnect that map through VN-link to a vNIC or VM itself) per fabric interconnect

Note    The only exception is for failover vNICs. These consume resources on a per UCS system basis.
