How to set up port speed in SRX4600

Description

This article describes possible speed combination and how to set port speed in SRX4600

Symptoms

You will see the following alarms after configuring the port speed:.

root@jtac-srx4600> show chassis alarms

2024-05-17 06:07:36 UTC Minor FPC 0 PIC 0 Invalid port profile configuration

Solution

The SRX4600 consists of the following ports:
- Four Chassis Cluster (HA) ports (referred to as PIC 0 ports of FPC 0)
- Four 40/100-Gigabit Ethernet QSFP28 ports (referred to as PIC 0 ports of FPC 1)
- Eight 1/10-Gigabit Ethernet SFP+ ports (referred to as PIC 1 ports of FPC 1)

The maximum capacity of an SRX4600 Firewall is 400 Gbps, which cannot be oversubscribed. To prevent oversubscription, configure the number of active ports operating at the desired speed by using the number-of-ports statement. After committing the configuration, a system or cluster reboot is required for the new configuration to take effect and to clear the alarms.

These are the possible speed combinations:

Note: In the interface Options 2, you can rearrange the speed of PIC0 as per your needs. This is just a sample and doesn’t mean that 100G should only be configured in port 0 and 1.

While configuring the speed in FPC 1 PIC 0, you must specify the speed for the remaining 8 ports of FPC 1 PIC 1. This ensures the PFE is programmed correctly for the connected optics.

Below is the configuration sample:

set chassis fpc 1 pic 0 port 0 speed 40g
set chassis fpc 1 pic 0 port 1 speed 100g
set chassis fpc 1 pic 0 port 2 speed 40g
set chassis fpc 1 pic 0 port 3 speed 100g
set chassis fpc 1 pic 1 port 0 speed 10g 
set chassis fpc 1 pic 1 port 1 speed 10g 
set chassis fpc 1 pic 1 port 2 speed 10g 
set chassis fpc 1 pic 1 port 3 speed 10g
set chassis fpc 1 pic 1 port 4 speed 10g 
set chassis fpc 1 pic 1 port 5 speed 10g 
set chassis fpc 1 pic 1 port 6 speed 10g 
set chassis fpc 1 pic 1 port 7 speed 10g

Or you can configure it the following way:

set chassis fpc 1 pic 0 pic-mode 100G
set chassis fpc 1 pic 0 number-of-ports 2
set chassis fpc 1 pic 1 pic-mode 1G
set chassis fpc 1 pic 1 number-of-ports 8
