Hi all,
In order to find unusual things on EX switch, I executed the junos cli of "clear interfaces statistics all" last Friday. Since then errors are shown below:
1-) From the following outputs, there are 2 collisions(Collisions: 1743 and Collisions: 48 ) are persistintly increasing. The following KB says that Collision always must be zero. Otherwise, there is a software bug.
https://kb.juniper.net/InfoCenter/index?page=content&id=KB24601. What troubleshooting should I do? More further why there is no other errors on these 2 interface as they have collisions errors?
It is realy weird.
2-) There is also number of "Carrier transitions:" from output below. One of them is very high and constantly increasing. what troubleshooting must be done for identifying issue.
4500>show interfaces extensive | match "Carrier transitions: [^0]| Errors: [^0]| Drops: [^0]|Collisions: [^0]|CRC errors: [^0]| MTU errors: [^0]"

Carrier transitions: 0, Errors: 0, Drops: 4, MTU errors: 0, Resource errors: 0
3-) Is there additional pipe that can be add into cli of "show interfaces extensive | match "Carrier transitions: [^0]| Errors: [^0]| Drops: [^0]|Collisions: [^0]|CRC errors: [^0]| MTU errors: [^0]"" to get associated Physical interfaces?
