3 Update Records

3.1 New Features

[BGP] Support for BGP As-Notation.
[SLA] IP SLA supports jitter metric calculation and display.
[Exporter] Support for ACL configuration and statistics counters, as well as VLAN statistics counters.
[VXLAN]CX308P-48Y-N-V2, CX532P-N-V2 and CX732Q-N-V2 support VXLAN Cross-Connect and L2PT.
[VXLAN] Support for BUM traffic replication via VXLAN multicast tunnels.
[AIDC]Dynamic intelligent routing scheme supports VLAN interfaces.

3.2 Major Bug Fixes and Optimizations

[Easy RoCE] Support for specifying lossless queues.
[PTP]Support for configuring the minor_version field in PTP messages.
[ARS] ARS supports for displaying the bound target Nexthop Group members.
[Easy RoCE] A prompt is added when an interface undergoes split and rate changes with an existing RoCE template.
[AIDC]The “show instance” command displays configuration check results.[MAC] Added a restriction that prevents removal from VLAN after disabling MAC learning on an interface.
[LLDP] Modified the maximum value displayed for TTL value to 65535 to prevent overflow.
[SLA] Fixed an issue where SLA couldn’t specify a Lag sub-interface as the src_port.
[AIDC] Fixed a BGP configuration failure when multiple router BGP instances with different ASNs exist.
[DHCP] Fixed an issue where relay instances with the same name across different VRFs weremistakenly treated as the same relay instance.
[BGP] Fixed an issue where BGP route advertisements failed when multiple unnumbered BGP neighbors had the same link-local address.
[Interfacel Fixed an issue where the interface of NT devices incorrectly counted received ARP request, IPv6 NS, and RA messages into RX DRP statistics.
