VFP |
There are 4 VFP slices, providing a total of 4*256 = 1024 entries.
All slices are allocated statically.
|
1 slice:
- to strip the transport VLAN 1 tag from outbound-CPU-originated
packets (to support egress mirroring of such traffic). This
requires 1 entry per system.
- to assign a virtual port (VP) to packets arriving on an untagged
bridged subinterface. This requires 1 entry per untagged bridged
subinterface.
|
3 slices for capture and system filter entries:
- Three physical slices are grouped to support triple-wide
entries.
- One triple-wide entry is consumed by each IPv4 capture-filter
entry, IPv4 system filter entry, IPv6 capture-filter entry, or
IPv6 system filter entry (the system supports mapping IPv4
groups and IPv6 groups onto the same physical slices); maximum
possible scale is 256 entries.
|
IFP |
There are 12 IFP slices on 7220 IXR-D4/D5, providing a total of 12*2K
= 24K entries.
|
On 7220 IXR-D5, all slices are allocated statically:
- 2 slices for CPU QoS queue assignment
- 1 slice for VXLAN ES-related functionality
- 2 slices for ingress IPv4 ACL
2K ingress IPv4 ACL entries are
supported by group of 2 side-by-side banks (inter-slice
double-wide mode). Maximum possible ingress IPv4 TCAM
entries = 2048
- 3 slices for ingress IPv6 ACL
2K ingress IPv6 ACL entries are
supported by group of 3 side-by-side banks (inter-slice
triple-wide mode). Maximum possible ingress IPv6 TCAM
entries = 2048
- 2 slices for MAC ACL
2K ingress MAC ACL entries are supported
by group of 2 side-by-side banks (inter-slice double-wide
mode). Maximum possible ingress MAC TCAM entries =
2048.
- 1 slice for ingress subinterface policing
|
On 7220 IXR-D5, all slices are allocated statically:
- 2 slices for CPU QoS queue assignment, providing 2048
entries
- 1 slice for VXLAN ES related functionality, providing 2048
entries
- 2 slices for ingress IPv4 ACLs, providing 1024 entries
- 3 slices for ingress IPv6 ACLs, providing 1024 entries
- 2 slices for MAC ACLs, providing 1024 entries
- 1 slice for ingress subinterface policing, providing 2048
entries
|
EFP |
There are 4 EFP slices providing a total of 4*512 = 2048 entries
|
1 slice is allocated statically. Entries serve 2 purposes:
- ES pruning of local-biased traffic. This requires 1 entry per
system.
- Egress port mirroring statistics. This requires 1 entry per
outgoing interface.
|
3 slices are available for dynamic allocation
- 2 physical slices are grouped to support double-wide
entries
- 3 physical slices are grouped to support triple-wide
entries
- 1 triple-wide entry is consumed by each interface egress IPv4
filter entry, interface egress IPv6 filter entry, IPv4 CPM
filter entry or IPv6 CPM filter entry (the system supports
mapping IPv4 groups and IPv6 groups onto the same physical
slices); maximum possible scale is 512 entries
- 1 double-wide entry is consumed by each interface egress MAC
filter entry or MAC CPM filter entry
