G
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.
Subject Maximum
IPv4 ACLs
total named (extended or standard) up to 2048 (minus any IPv4
numeric standard or extended
ACL assignments and any
RADIUS-assigned ACLs)
1
total numeric standard up to 99
1
total numeric extended up to 100
1
total ACEs in all IPv4 ACLs up to 3072
1
IPv6 ACLs
total IPv6 ACLs up to 2048
1
total ACEs in all IPv6 ACLs up to 3072
1

Actual 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 IPv6
2
IP addresses per VLAN 32
3
static routes 256
supported routes 10,000 (including ARP)
2
These 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.
3
There 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
