Interfaces

Logical interfaces limit expansion (SRX1600, SRX4120, SRX2300, and SRX4300)—The device raises the logical interface limit from 4000 to 8000 for large-scale deployments requiring more VLANs or tunnel interfaces. You cannot configure 8000 IFLs on one revenue port because the IEEE 802.1Q VLAN ID field uses 12 bits, limiting VLANs to 4095. Overcome this limitation by using two or more revenue ports to configure more than 4000 IFLs. Review platform prerequisites and operational impacts.

QSFP breakout channelization for 4x10G on PIC port 0 with fixed subports 1–4 (SRX4700)—Use QSFP breakout optics to enable 10 G breakout on PIC port 0 by setting 4x10G channelization in port-profile config-D. Only port 0 supports 4x10 Gbps on a 1x400 Gbps/4x100 Gbps/8x50 Gbps PIC, with a fixed range of one through four subports. Configure port 0 to 4x10 Gbps, 3x10 Gbps, 2x10 Gbps, or 1x10 Gbps. Use the set chassis fpc <fpc slot> pic <pic slot> port <port number> channel-speed <10G | 25G> command to configure channelization. Commit changes with any configuration or deletion of unused settings on port one to ensure deterministic behavior. [See Port Speed on SRX4700 Firewalls.]
