IPv6 BGP peers and IPv6 prefixes for non default VRFs are supported starting EOS 4.15.0F. All CLI commands available

EOS by default selects the prefix for ECMP if the two paths have the same AS PATH length regardless of the ASN values in

BGP Prefix Independent Convergence (PIC Edge) refers to fast re-convergence of traffic destined for BGP prefixes on a network event affecting the best path(s) such that the time taken to switch traffic from the active best path(s) to the next best path (i.e. backup path) is independent of the number of prefixes. The above behavior is achieved by pre-programming the best path and alternate backup path in the forwarding agent in steady state. 

BGP sFlow export is to add BGP route information including source and destination AS path information, local

In order to use the BST(Binary Search Tree) resources more efficiently for multicast, we are introducing a new CLI

Starting with EOS4.15.0F, dynamic and symmetric LAG hashing policies are supported on the 7500E platform. Dynamic

This feature allows generating the syslog message for the packets matching deny rules in egress ACLs. This can be enabled using the log keyword when configuring a deny ACL rule. A copy of the packet matching such deny ACL rule is sent to the control plane, where a syslog entry for the packet header is generated.

IPv4/IPv6 over MPLS packets are now eligible for ACLs at egress stage by default. The feature is applicable only to

Starting EOS 4.15.0F, EOS can monitor (for long durations) low error rate errors on all fabric links. It

LANZ is the EOS Latency and congestion ANalyZer. On DCS-7280, DCS-7020, DCS-7500 and DCS-7800 series, it allows monitoring congestion and transmit latencies on both front panel and CPU ports.

Loop protection is a loop detection and prevention method which is independent of Spanning Tree Protocol (STP) and is not disabled when the switch is in switchport backup mode or port is in discarding state. The LoopProtect agent has a method to detect loops and take action based on the configuration by the user. In order to find loops in the system, a loop detection frame is sent out periodically on each interface that loop protection is enabled on. The frame carries broadcast destination MAC address, bridge MAC source address, OUI Extended EtherType 0x88b7 as well as information to specify the origins of the packet.

For packets sent and received on the front-panel interfaces, this feature allows creation of a profile to configure buffer reservations in the MMU (MMU = Memory Management Unit which manages how the on-chip packet buffers are organized). The profile can contain configurations for ingress and egress. On the ingress, configuration is supported at both a port level as well as a priority-group level.
