Hi,

 

17:22:03.855288 SCN Port Offline;g=0x1264                   D2,P0  D2,P0  127   NA

 

### port 127 goes offline


17:22:03.855295 *Removing all nodes from port               D2,P0  D2,P0  127   NA
17:22:03.915549 SCN Port Offline;g=0x1266                   D2,P0  D2,P0  111   NA

 

### port 111 goes offline


17:22:03.915556 *Removing all nodes from port               D2,P0  D2,P0  111   NA
17:25:54.357454 SCN LR_PORT(0);g=0x1266                     D2,P0  D2,P0  111   NA

 

### As part of bringing up port 111, a Link Reset (LR) is done - think from 111 (check portshow LR_out vs LR_in)

 

17:25:54.357467 SCN Port Online; g=0x1266,isolated=0        D2,P0  D2,P1  111   NA

 

### Port 111 Online


17:25:54.357522 Port Elp engaged                            D2,P1  D2,P0  111   NA

 

### Elp = Exchange Link Parameter (setting)


17:25:54.357540 *Removing all nodes from port               D2,P0  D2,P0  111   NA
17:25:54.357912 SCN Port F_PORT                             D2,P1  D2,P0  111   NA

 

### port 111 is connected as F_Port

 

So, to summarize, port 127 went offline (check errlog etc), and port 111 went offline and then online again.

Notice that port 111 was offline for almost 4 minutes, which a looong time (maintenance ?)

 

Check the error counters for port 111 and 127 if any new errors have been logged. Check the errlog (errlog) and/or portlogdumpport 111 for some more details.

Hi,

the portlogdump is a circular buffer (16384 entries), so the probably the events for port 111 (and 127) is long gone. You need to capture the output from portlog with either portlogdump (for all ports) or portlogdumpport say within immediately on a busy switch (much port login or connected to several other switches), or in general within 15 minutes of the event.
