EVPN Multihoming

EVPN multihoming is a replacement mechanism for MLAG in EVPN deployment based on standard protocol (BGP-EVPN). In one customer site, a server can connect to two or more VTEP switches in order for redundancy. Additionally, the peer-link between MLAG spines is not needed in EVPN multihoming site. Please have the details by reference of document EVPN Multihoming Configuration Guide.

New BGP Commands

Add new BGP commands to configure confederation, dampening, local-preference, fast-external-failover, and prefix limits. Please have the details by reference of document BGP Commands.

Unnumbered BGP

With unnumbered BGP, it's not necessary to configure IP address of the BGP neighbor. The IPv6 link local is used to build BGP session from one hop to the next hop. The link local address of the BGP neighbor can be discovered by IPv6 ND (Neighbor Discovery) automatically.

Telemetry Based on gRPC/gNMI

The controller or network management system such as AmpCon can access to telemetry data on the switch remotely via gRPC/gNMI in order for monitoring the performance and status of the switch. The gRPC operations including CapabilityRequest, GetRequest, SetRequest, and SubscribeRequest are supported. The telemetry data including interfaces and LLDP is covered in PICOS 4.3.0 so far.

LACP Fast Mode

Support LACP fast mode. Under LACP fast mode, LACP control packets are sent to an LACP-enbled port per 1 second instead of 30 seconds under slow LACP mode.

SNMPv3 Trap

If SNMPv3 is enabled, SNMP trap messages will be sent out in SNMPv3 format under OVS mode.

Update Session Token

Once you are on the NPB web page, the current session token can be updated automatically during GUI activity when the timeout of the old token expires after 30 minutes without the need to re-login.

Port LED Issue on AS5835

When traffic goes through QSFP port, xe-1/1/1 or xe-1/1/4, the port LED doesn't blink. This issue is fixed in 4.3.0.

Sort Output in Interface Index

In certain CLI outputs, the interfaces are listed by the alphabetical order. Therefore, for example, ge-1/1/2 may follow ge-1/1/11. The interfaces should be sorted by the order of interface indices, i.e., ge-1/1/2 should go before ge-1/1/11.

Fix CoPP Statistics Error

When "run show copp statistics", may display arbitrary statistics numbers over CoPP protocol classes. This issue is fixed in 4.3.0.

Memory Leak Caused by NETCONF Process

When a NETCONF client accesses to the switch via RADIUS authentication repeatedly, memory leak may occur in process pica_netconf. This issue is fixed in 4.3.0.

Keep Sending RADIUS Request Messages

If configure RADIUS authentication and then enable NETCONF, the switch will keep sending RADIUS request Messages out. This issue is fixed in 4.3.0.

Drastic Variation over CPU Utilization

The number of CPU utilization may change drastically and fastly on AS4610. This issue is fixed in 4.3.0.

Failed to Add pop_vxlan Flow

Only a few vxlan_pop flow entries can be added. This issue is fixed in 4.3.0.
