ETHERNET

Ethernet Interfaces

• Port 1: RJ45, 10/100/1000Base-T, PoE
• Port 2: SFP cage which support regular SFP 1Gb/s (Eth 2), or CSFP 1Gb/s (Eth2 + Eth3)
• Port 3:  Two options:
o 1x10/100/1000Base-T used for management only; OR
o SFP cage which support regular SFP 1 Gb/s (Eth1), or SFP+ 10Gb/s (Eth1)
Note: SFP devices must be of industrial grade (-40°C to +85°C)

Ethernet Features

• MTU – 9600 Bytes
• Quality of Service
o Multiple Classification criteria (VLAN ID, p-bits, IPv4, DSCP, IPv6 TC, MPLS EXP)
o 8 priority queues per port
o Deep buffering (configurable up to 64 Mbit per queue)
o WRED
o P-bit marking/remarking
• 4K VLANs
• VLAN add/remove/translate
• Frame Cut Through – controlled latency and PDV for delaysensitive applications
• Header De-Duplication – Capacity boosting by eliminatinginefficiency in all layers (L2, MPLS, L3, L4, Tunneling – GTP for LTE, GRE)**Note: not available for 500MHz channel
• Adaptive Bandwidth Notification (ABN), also known as EOAM
