RACL on inner IP fields for VXLAN decapsulated packets

Description This feature introduces the support for ACL configuration on VxLAN decapsulated packets. The configured ACL rules will be applied to the inner packet header after Vxlan header decapsulation. The ingress RACLs for VxLAN decap packets can be configured on SVIs or under Vxlan tunnel interface. Platform Compatibility DCS-7280R/R2 DCS-7500R/R2 Configuration No special configuration needed to enable RACLs on SVIs to match inner header fields for VxLAN decapsulated packets. interface Vlan100 ip address 1.0.5.1/24 ip access-group vxlanAclIpv4CoreToEdge in ! interface Vxlan1 vxlan source-interface Loopback0 vxlan udp-port 4789 vxlan vlan 100 vni 20000 vxlan flood vtep 172.16.1.1 172.16.1.2 172.16.1.3 ! ip...

Ingress/Egress per-port IPv4, IPv6 counters

This feature provides support for per-interface ingress/egress packet/byte counters for both IPv4 and IPv6. Platform compatibility DCS-7280SR DCS-7280CR DCS-7500-R DCS-7300X DCS-7250X DCS-7050X DCS-7060X Please note feature is platform specific, packet versus bytes distinction, and the ability to count routed packets only (as opposed to counting all IPv4/v6 traffic: routed or bridged). Please consult your systems engineer to check if a particular combination is supported. Configuration IPv4, IPv6 ingress counters (counts bridged and routed traffic, supported only on front-panel ports) can be enabled/disabled using the following command: Arista#[ no ] hardware counter feature ip in For IPv4, IPv6 ingress/egress counters that...

Nexthop group counters

The nexthop group feature allow users to manually configure a set of tunnels. Nexthop group counters provide the ability to count packets and bytes associated with each tunnel nexthop, irrespective of the number of times it appears in one or more nexthop groups. In other words, if a nexthop group entry shares a tunnel resource with another entry, they will also share the same counter. In 4.20 and later, if sharing counters is not desired, per-entry nexthop group counters can be configured within each nexthop group at the cost of additional tunnel resources. Supported platforms DCS-7500 DCS-7280 Configuration Configure the counter feature to...
