Minor alarm

Log message 

The SRX5K-IOC4-MRATE supports an aggregate bandwidth of 480 Gbps, and each of the two PICs supports a bandwidth limit of 240 Gbps.

If the aggregate port capacity configured exceeds 240 Gbps per PIC, the configuration is not supported.

A minor alarm will be generated if the ports are oversubscribed that the bandwidth limit of each PIC on the IOC4 card.

Port Configuration:

[edit chassis fpc 5 pic 0]
root@b01-17# show
port 0 {
    speed 40g;
}
port 1 {
    speed 40g;
}
port 2 {
    speed 100g;
}
port 3 {
    speed 100g;
}

In the above configuration, the total speed equals 280G which exceeds the PIC bandwidth limit.

Modify the configuration settings to ensure the maximum configured speed is set to 240 Gbps or lower.

Note: When you change an existing port speed configuration with an invalid port speed configuration, an alarm is generated indicating that the port speed configuration is invalid. The MPC continues to operate using the previously configured valid port speed configuration. However, if the MPC or PIC is restarted with the committed invalid port configuration, all ports of the MPC operate as four 10-Gigabit Ethernet interfaces by default.
