Ethernet Switch TSN 20x1G + 4x5G
Key Features
- 20 ports of 1 Gigabit Ethernet.
- 4 ports of 5 Gigabit Ethernet.
- Full wire-speed on all ports and all Ethernet frame sizes.
- Store and forward shared memory architecture.
- Support for jumbo packets up to 32749 bytes.
- Passes maximum overlap mesh test (RFC2899) using all ports for all packet sizes up to 1518 bytes.
- Time-Sensitive Networking:
- IEEE Std 802.1Qci-2017: Per-Stream Filtering and Policing
- IEEE Std 802.1CB-2017: Frame Replication and Elimination for Reliability
- IEEE Std 802.1Qbv-2015: Enhancements for Scheduled Traffic
- IEEE Std 802.1Qav-2009: Credit Based Shaper
- Queue management operations:
- Disable scheduling of packets on a port.
- Disable queuing new packets to a port.
- Allow a port to be drained without sending out packets.
- Allow checking if a port is empty or not.
- Input and output mirroring.
- RSPAN - Remote Switch Port Analyzer
- 4 source MAC address ranges with a number of different actions.
- 4 destination MAC address ranges with a number of different actions.
- 1,024 entry L2 MAC table, hash based 4-way.
- 4,096 entry VLAN table.
- 16 entry synthesized CAM to solve hash collisions.
- 4 entries of the synthesized CAM are fully maskable.
- 64 entry L2 multicast table.
- Automatic aging and wire-speed learning of L2 addresses. Does not require any CPU/software intervention.
- Spanning tree support, ingress and egress checks.
- 16 multiple spanning trees, ingress and egress checks.
- Egress VLAN translation table allowing unique VID-to-VID translation per egress port.
- VLAN priority tag can bypass VLAN processing and be popped on egress.
- 496 entries of ingress classification / ACL Lookups. The classification / ACL keys are configurable for each source port and the fields are selected from a incoming packets L2, L3 or L4 fields. The selection is described in 10.2 The classificaiton / ACL key can be up to 372 bits long. The classification / ACL lookup is based on a combination of hash and TCAM. The actions which can be done is listed below:
- Multiple actions can be assigned to each result. All results can be done in parallel if the user so wishes.
- Result action can be to drop a packet.
- Result action can be to send a packet to the CPU port.
- Result action can be to send a packet to a specific port.
- Result action can be to update a counter. There are 32 counters which can be used by the classification / ACL engine.
- Result action can be to force packet to a specific queue on a egress port.
- Result action can be to assign a meter/market/policer to measure the packet bandwidth.
- Result action can be to assign a color to the packet which is used by the meter/marker/policer.
- Result action can be to force the packet to use a specific VID when doing the VLAN table lookup.
- Result action can be to do a input mirror on a packet.
- Result action can be to not allow the packet to be learned in L2 MAC table.
- The ingress configurable classification / ACL engine can use the type and code fields from ICMP frames.
- The ingress configurable classification / ACL engine can use the fields, including the group address, from IGMP frames.
- 1843200 bits shared packet buffer memory for all ports divided into 1536 cells each of 150 bytes size
- 8 priority queues per egress port.
- Configurable mapping of egress queue from IP TOS, MPLS exp/tc or VLAN PCP bits.
- 32 ingress admission control entries.
- Deficit Weighted Round Robin Scheduler.
- Bandwidth shapers per port.
- Individual bandwidth shapers for each priority on each port.
- Individual bandwidth shapers for each queue on each port.
- Egress queue resource limiter with four sets of configurations.
- Configuration interface for accessing configuration and status registers/tables.
- Multicast/Broadcast storm control with separate token buckets for flooding, broadcast and multicast packets.
- Multicast/Broadcast storm control is either packet or byte-based, configurable per egress port.
- LLDP frames can optionally be sent to the CPU.
- Attack prevention by TCP flag rules combined with TCP-port and IP address checks, this also includes IMCP length attack checks.
