Hello everyone,
Currently, the FPR equipment and C9300 equipment are connected with an optical cable.
It was a cable that had been in good use before.
One of the FPR2130 devices failed and was restored to its original state.
But the problem is that the data link port is behaving strangely.
Problem 1. The physical status of FPR2130 (Port LED) blinks green. The FPR2130 next to it, which is operating normally, also blinks green when it is in normal operation.
However, when I check the interface in FCM, it shows Down. Even in ASA OS, the port appears as link down.
Problem 2. When connecting the optical cable of FPR2130 in C9300, the log clearly shows UP. However, if you look at Show interface Status, it shows DOWN, but DOWN is not actually recorded in the C9300's log.
The physical configuration is like this.
FRP2130 HA configuration (Act / Std) -> ASA OS, Multiple context mode + All contexts operate in Transparent.
Two C9300 (Stacking) units are in operation at the bottom of FPR2130 HA.
The connection between one FPR2130 and one C9300 is set to Port-channel with two optical cables.
In C9300, only switch mode trunk and channel-group settings are set.
The port-channel of the C9300 has no special settings, only trunk mode settings.
The problematic FPR2130 device port settings are the same as the port settings currently in normal operation, and the FCM settings were also set based on normal operation.
The configuration of the problematic FPR2130 was copied from a normally operating FPR2130 when configuring HA, so it is unlikely to be Misconfig.
Currently planned measures include replacing the optical cable patch cord and changing GLC-SX-MMD.
Is there anything else I should check?
Thanks
