Description

• One, two, four, or ten Gigabit Ethernet ports
• Power requirement:
  • 1-port: 0.25 A @ 48 V (11.9 W)
  • 2-port: 0.25 A @ 48 V (11.9 W)
  • 4-port: 0.50 A @ 48 V (23.8 W)
  • 10-port: 0.62 A @ 48 V (29.9 W)
• Supports large Ethernet frame sizes for more efficient throughput across the intra-POP network

Software features

• Virtual Router Redundancy Protocol (VRRP) support
• 802.1q virtual LANs (VLANs) support
• 960 destination MAC filters per port
• Optical diagnostics and related alarms on the 2-port, 4-port, and 10-port PICs (Junos OS Release 8.2 and later)
• 64 source MAC filters per VLAN on the 1-port, 2-port, and 4-port PICs
• 1024 source MAC filters per port on the 1-port, 2-port, and 4-port PICs
• Flexible Ethernet encapsulation on the 1-port, 2-port, and 4-port PICs
• Multiple tag protocol identifiers (TPID) support on the 1-port, 2-port, and 4-port PICs
• Source MAC learning on the 1-port, 2-port, and 4-port PICs
• MAC accounting and policing—Dynamic local address learning of source MAC addresses on the 1-port, 2-port, and 4-port PICs
• Passive monitoring for IPv4 packets on the 10-port PIC for Junos OS Release 11.1 and later.

Note: The 10-port Gigabit Ethernet PIC with SFP does not support MAC accounting and policing, MAC learning, TPID, or flexible Ethernet encapsulation. 64 source MAC filters per port.

LEDs

Status LED, one bicolor:

• Off—PIC is not enabled.
• Green—PIC is operating normally.
• Red—PIC has an error or failure.

Port LEDs, one pair per port:

• Link—If green, the port is online; if there is no light, the port is down.
• Activity—If flashing green, the port is receiving data; if there is no light, the port might be on but is not receiving data.
