VLAN scaling guidelines

The number of recommended VLANs differs between the modes as SmartFabric mode provides network automation capabilities that Full Switch mode does not.

The following table lists the maximum number of VLANs recommended per fabric, Uplink, and server port:

Table 1. Maximum number of VLANs recommended in SmartFabric modeThe following table lists the maximum number of VLANs recommended in the SmartFabric mode:
OS10 Version	Parameter	Value
10.5.4.1	Maximum VLANs per fabric	3000
	Maximum VLANs per uplink	3000
	Maximum VLANs per server port	1500
10.5.3.X	Maximum VLANs per fabric	3000
	Maximum VLANs per uplink	3000
	Maximum VLANs per server port	1024
10.5.2.4 and 10.5.2.6	Maximum VLANs per fabric	1536
	Maximum VLANs per uplink	1536
	Maximum VLANs per server port	512
10.5.1.6-10.5.1.7	Maximum VLANs per fabric	512
	Maximum VLANs per uplink	512
	Maximum VLANs per server port	256
10.5.0.1-10.5.0.7	Maximum VLANs per fabric	256
	Maximum VLANs per uplink	256
	Maximum VLANs per server port	64
10.4.0.R3S 10.4.0.R4S	Maximum VLANs per fabric	128
	Maximum VLANs per uplink	128
	Maximum VLANs per server port	32

NOTE: For instructions on enabling SmartFabric Services to support higher VLAN counts (more than 256 VLANs per fabric), see the Dell PowerEdge MX Networking Deployment Guide available at https://infohub.delltechnologies.com/t/mx-series-modular-switches-poweredge-mx-7/.

Configuration guidelines for VLAN scale spanning tree

Table 2. Configuration guidelines for VLAN scale (STP flavor)The following table provides the details of number of VLANs configured in each IOM:
Scale	STP flavor
Number of VLANs configured in each IOM is less than 100	RPVST or RSTP can be configured.
Number of VLANs configured in each IOM is greater than 100	RSTP is the recommended configuration.

Table 3. Configuration guidelines for VLAN scale (VLAN configuration)
Scale	Scale-profile VLAN configuration
Number of port vlan (PV) combinations is less than 6144	Not required
Number of port vlan (PV) combinations is greater than 6144	Is mandatory

NOTE: For more information about scale-profile VLAN, see Dell PowerEdge MX Networking Deployment Guide available at https://infohub.delltechnologies.com/t/mx-series-modular-switches-poweredge-mx-7/.
