ACL Slices and Rules
The ExtremeSwitching series switches use a mechanism different from the earlier ExtremeSwitching series to implement ACLs. The same
architecture and guidelines apply to both
platforms.
Instead of the per port masks used in earlier switches, these
platforms use slices that can apply to any of the supported ports.
An ACL applied to a port may be supported by any of the slices.
The slice support is as follows:
- 4120 switches—
- Eight ingress stage slices with 2,000 single-wide rules
- Four VLAN look-up stage slices with 512 rules
- Four egress stage slices with 512 rules
- 4220 switches—
- Eight ingress stage slices with 2,000
single-wide rules
- Four VLAN look-up stage
slices with 512 rules
- Four egress stage slices with 512 rules
- ExtremeSwitching 5320 switches—
- Four VLAN look-up stage
slices with 1,024 rules for 5320-48TP models.
- Eighteen ingress stage slices with 16,000
single-wide rules for 5320-48T/P and 24 and 16-port models.
- Eighteen ingress stage slices with 8,000
double-wide rules for 5320-48T/P and 24 and 16-port models.
- Four egress stage slices
with 1,024 rules for 5320-48T/P models.
- Four VLAN look-up stage slices with 512
rules for 5320-24 and 16-port variants models.
- Four egress stage slices with 512 rules for
5320-24 and 16-port variants.
