---

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.	2000
IGMP groups per system	1000
EtherChannels per fabric interconnect	16
Member interfaces per EtherChannel	16
Primary VLANs per system	30 Note    Private VLANs count towards the total number of VLANs.
Secondary VLANs per system	30
QOS system classes per system	6 (including the class default)
Dynamic virtual NICs per VIC	56 Note    Dependent on the OS. ESX supports 56 dynamic vNICs in ESX, versions 4.0 and 4.1.
Static virtual NICs per VIC	OS	VNICs	vHBAs
	Win 2003	10	2
	Win 2008 Note    Total maximum combination of vNICs and vHBAs is limited to 20.	20	16
	RHEL 5.4 Note    Total maximum combination of vNICs and vHBAs is limited to 32.	32	16
	ESX 4UI Note    Total maximum combination of vNICs and vHBAs is limited to 26.	26	16

Table 2 Fibre Channel Environments

Feature	Cisco UCS 6100 Series
VSANs	32
Zones	Default zoning is disabled on a per VSAN basis. Note    Zoning is not natively supported on the 6100 series fabric interconnects. Zones can be uploaded from MDS or Nexus 5000.
Native 4G FC links in the 6120	8 Note    4G Fibre Channel links are supported on expansion model N10-E0080 (8 1/2/4 Gbps ports)
Native 4G FC links in the 6140	16
Native 8G FC links in the 6120	6 Note    8G Fibre Channel links are supported on expansion model N10-E0060 (6 1/2/4/8 Gbps ports)
Native 8G FC links in the 6140	12
Virtual Fibre Channel interfaces per fabric interconnect	160
Virtual Fibre Channel interfaces per blade interconnect	32
Flogis per Fibre Channel module	255

Table 3 VM-FEX (PALO PTS) Environments

Feature	Cisco UCS 6100 Series
VMs per blade	54 with 2 vHBAs 56 without vHBAs
Hosts per DVS	60
DVSs per system	8
vCenters per system	8
Port profiles per system	180

Table 4 General Parameters

Feature	Cisco UCS 6100 Series
Chassis per system	20
MAC table size per system	32000 entries 5001 entries are reserved as multicast MAC addresses; the usable limit for unicast MAC addresses is 13,800.
Secured interfaces per system	1000 1000 out of the 2000 VIFs can be port-secured.
Secured MAC addresses per system	2000 MAC addresses secured using the port-security feature.
Maximum MTU	9000
1G ports per 6120	First 8 fixed ports
1G ports per 6140	First 16 fixed ports
IP storage appliances per fabric interconnect	2 IP storage applicances per fabric interconnect are validated. No software limitations.
SPAN active sessions per fabric interconnect	2
