Hey,
we have a running mesh infrastrucure which consists out of four 5406Rzl2 Switches. So everyone is connected to every other switch in this mesh.
Like this:
1--2
| \/ |
| /\ |
3--4
Since fwe days we get warnings of the interfaces which connects Switch 2 and 3. It says: "...port X-High collision or drop rate. See help"
I've checked the Interface speed which is 10Gig auto on both sides, and the int details:
Switch 2:
Name : Mesh Switch 2 to 3
MAC Address : XXXX
Link Status : Up
Port Enabled : Yes
Totals (Since boot or last clear) :
Bytes Rx : 3,604,846,339 Bytes Tx : 2,607,369,036
Unicast Rx : 3,333,818,006 Unicast Tx : 3,916,313,969
Bcast/Mcast Rx : 2,435,991 Bcast/Mcast Tx : 3,403,390
Errors (Since boot or last clear) :
FCS Rx : 0 Drops Tx : 94,627,981
Alignment Rx : 0 Collisions Tx : 0
Runts Rx : 0 Late Colln Tx : 0
Giants Rx : 0 Excessive Colln : 0
Total Rx Errors : 0 Deferred Tx : 0
Others (Since boot or last clear) :
Discard Rx : 19,610 Out Queue Len : 0
Unknown Protos : 0
Rates (5 minute weighted average) :
Total Rx(Kbps) : 974,776 Total Tx(Kbps) : 202,264
Unicast Rx (Pkts/sec) : 105,849 Unicast Tx (Pkts/sec) : 32,628
B/Mcast Rx (Pkts/sec) : 9 B/Mcast Tx (Pkts/sec) : 10
Utilization Rx : 09.74 % Utilization Tx : 02.02 %
And Switch 3:
Name : Mesh Switch 3 to 2
MAC Address : XXXX
Link Status : Up
Port Enabled : Yes
Totals (Since boot or last clear) :
Bytes Rx : 4,194,119,049 Bytes Tx : 927,205,841
Unicast Rx : 4,007,124,479 Unicast Tx : 3,740,001,825
Bcast/Mcast Rx : 761,718,019 Bcast/Mcast Tx : 1,443,420,354
Errors (Since boot or last clear) :
FCS Rx : 0 Drops Tx : 5,316,789
Alignment Rx : 0 Collisions Tx : 0
Runts Rx : 0 Late Colln Tx : 0
Giants Rx : 0 Excessive Colln : 0
Total Rx Errors : 0 Deferred Tx : 0
Others (Since boot or last clear) :
Discard Rx : 11,705 Out Queue Len : 0
Unknown Protos : 0
Rates (5 minute weighted average) :
Total Rx(Kbps) : 389,224 Total Tx(Kbps) : 691,856
Unicast Rx (Pkts/sec) : 43,886 Unicast Tx (Pkts/sec) : 75,284
B/Mcast Rx (Pkts/sec) : 9 B/Mcast Tx (Pkts/sec) : 13
Utilization Rx : 03.89 % Utilization Tx : 06.91 %
So there are lots of drops on these interfaces even if the Utilization isnt at 100%.
I've checked the int details again some seconds later an the Utilization has decreased but the drops increased.
If I do "show mesh" there is also a Mesh warning on Switch 3. On Switch 2 there isnt.
Can anyone help?
