141744.2.3

Routed Interface

A routed interface and multiple sub-interfaces can be configured on a physical port or a LAG port. As L3 interfaces, the routed interface and associated sub-interfaces are layer 3 interfaces which can be assigned with IP addresses and configured with routing protocols for communication with other layer 3 routing devices. Please have the details by reference of document Configuring Routed Interface.

141824.2.2.2

Maximum Session Number on NAC Port

Allow to configure maximum number of authorization sessions on NAC ports. It can be configured globally or as per a specific port. The number configured on a specific port takes higher priority. Please have the details by reference document set protocols dot1x interface max-sessions and set protocols dot1x max-sessions-per-port.

140434.2.2

PVLAN Enhancement

Multiples normal VLANs can be configured on a PVLAN ports. A secondary community or isolated VLAN can be configured to a pvlan-secondary-trunk port from NAC server dynamically if 802.1X or MAB authentication is succeeded.

140494.2.2

OSPF ASBR External Route Summarization

Summarization of external redistributed routes as Type-5 external LSAs can be done on the ASBR before injecting them into the OSPF domain. Without summarization, all the redistributed external prefixes from external autonomous systems are passed into the OSPF area. This feature can be used to reduce the size of the OSPF LSDB.

140384.2.2

Cover Tunnel and Loopback Interfaces in "run show vrf"

In the output of CLI command "run show vrf" under operational mode, tunnel and loopback interfaces are included in additional to VLAN interfaces.

141044.2.2

Overlapping IP Addresses on GRE Tunnel Interfaces in Different VRF Instances

Overlapping IP addresses can be configured on GRE tunnel interfaces within different VRF instances.

139604.2.1

Multiple Loopback Interfaces

Within a user configured or the default VRF, multiple loopback interfaces can be configured. The built-in loopback interfaces such as lo in the default VRF are still available. Additionally, the loopback interfaces can get down or up by disabling or enabling them.

139974.2.1

GRE Source Interface

Support to configure a loopback interface or a L3 VLAN interface to a GRE tunnel. If multiple IP addresses are configured on the source interface, the smallest IP address will be the source IP address of this GRE tunnel.

140244.2.1

GRE IPv6 Support

IPv6 payload can be carried in IPv4 GRE tunnel.

140064.2.1

sFlow Next Hop Router

IP address of next hop router, covered in extended router data of sFlow version 5, is included in the samples of IP packets.

140054.2.1

LACP Fallback under Preemptive Mode

Under preemptive mode of LACP fallback, it's always the member port of a LAG with the highest priority that will keep alive.

139944.2.1

Flood Unregistered Multicast Traffic in VLAN with IGMP Snooping Enabled

By default, if IGMP snooping is enabled on a VLAN, the unregistered multicast traffic can be only forwarded out of mroute ports. If turn on flood-all, the unregistered multicast traffic will be flooded out of all ports within the VLAN even with IGMP snooping enabled.

139924.2.1

ABR Route Summarization for OSPF

For an OSPF area, you can summarize and filter intra-area prefixes. All routes that match the configured area range are filtered at the ABR (Area Border Router). And only the summary is advertised to the other areas. That can prevent a large number of link-state records from being flooded out of the area.

139464.2.1

Add Support for BGP Delay Open Timer

This BGP command is used to delay sending an OPEN message for a specific time period. The delay allows the remote BGP Peer time to send the OPEN message first.

Increase the limit of NAC servers. Allow to configure 20 NAC servers with different priorities.

140414.2.1

Display GRE Tunnel Interface

131624.2.0

GRE Tunneling

Generic Routing Encapsulation (GRE) is used for tunneling IP traffic via virtual point-to-point links over IP network. The overlay traffic can be isolated by different VRFs. Please refer to Generic Routing Encapsulation Protocol (GRE) for more details.

136594.2.0

BFD Support

Bidirectional Forwarding Detection (BFD) is a detection protocol purposed for fast forwarding link failure detection. PICOS BFD supports BGP, OSPF, and PIM. Please refer to Bidirectional Forwarding Detection (BFD) for more details.

Support 100G QSFP28 CWDM4

QSFP28 CWDM4 optical transceivers can work with PICOS 4.2.0.

138664.2.0

Interface Name VS. Physical Port Index

The names of uplink ports are not consistent with their physical indices such as 49 is the physical index of interface te-1/1/1 on AS4610_54P. A new CLI command "show interface port-index-mapping" under operational mode is added to show the map between interface names and physical port indices. Additionally, in the output when execute "run show interface brief" and "run show interface diagnostics optics xxxx", a physical port index in parenthesis will follow the interface name if they don't match to each other.

139044.2.0

Inband Management VLAN Interface

Remove the limitation that inband management can be enabled on only maximum 4 VLAN interfaces. Additionally, inband management can be enabled on all interfaces globally.

138894.2.0

137094.2.0

VXLAN Statistics 

With regarding to a specific VXLAN instance identified by a VNI number, VXLAN counters are used for tracking the Rx/Tx number of traffic on access port and network port respectively.

138944.2.0

Enhancement on MLAG Consistency Checking

In case of type 2 of MLAG inconsistent configuration, it is not necessary to show "FAIL" because the peer-link and MLAG ports will not be blocked. When execute CLI command "run show mlag consistency-parameter summary", will display "PASS with ALERT" in the overview/global result and "ALERT" by following each specific type 2 item which doesn't match to the configuration on the peer MLAG spine switch.
