Scalability: IP Address, VLAN, and Routing Maximum Values

The following table lists the switch scalability values for the areas of VLANs, ACLs, hardware, ARP, and routing.

1Actual availability depends on combined resource usage on the switch. Refer to Appendix E, “Monitoring Resources”.

Layer-3

 

VLANs with at least one IP Address

512

IP addresses per system

2048 IP

 

2048 IPv62

IP addresses per VLAN

323

static routes

256

supported routes

10,000 (including ARP)

2These limits apply only to user-configured addresses and not to auto-configured link local and prefix IPv6 addresses. A maximum configuration could support up to 2048 user-configured and 2048 auto-configured IPv6 addresses for a total of 4096.

3There can be up to 32 IPv4 and 32 user-configured IPv6 addresses on a single VLAN. In addition, each VLAN is limited to 3 auto-configured prefix-based IPv6 addresses.
