Recently received a problem ticket indicating a threshold violation on Eobc 0/0. This is occurring on a 6509 with software 12.2(33)SXI8. When doing a 'show eobc" I see the following: Interface information: Interface EOBC0/0 (idb = 0x50AD5524) Hardware is Mistral EOBC (revision 5) Address is 0000.1500.0000 (bia 0000.1500.0000) Encap size         = 14         hardware status  = 0x210840 IDB type           = 18         IDB state        = 4 Encap type         = 0x1        Span encap size  = 0 Error threshold    = 5000       Error count      = 0   Counters: rxring             = 0x921D940  rx ring entries       = 512        rx_head            = 248        rx_tail               = 0 inputs             = 7041590557 rx_cumbytes           = 2685550134617 hw inputs          = 0          hw rx_cumbytes        = 0 rx rate (bits/sec) = 629000     rx rate (packets/sec) = 216 rx_buf_unavail     = 0          rx input drops        = 299        input broadcast    = 25         input resource        = 1531956409 input error        = 0          input giants          = 0 input crc          = 299        rx illegal length     = 0 rxr eobc shadow    = 0x50BE2C20 txr eobc shadow       = 0x47B3DC00   txring             = 0x921F980  tx ring entries       = 0x200 tx_head            = 52         tx_tail               = 52 outputs            = 6628559346 tx_cumbytes           = 559065790427 hw outputs         = 0          hw tx_cumbytes        = 0 tx rate (bits/sec) = 130000     tx rate (packets/sec) = 207 tx_retry_error     = 471        tx_retry_count        = 17642354 tx_process_stopped = 96         tx total drops        = 0   Mistral Registers soft_reset_cfg     = 0x040000   dma_buffer_size_reg   = 0x000000 int_mask_hi        = 0x00007E   int_mask_lo           = 0xE7001A58 rxdscp_cnt         = 512        txdscp_cnt            = 0 rxwork_dscp        = 0xE8C0     txwork_dscp           = 0xFB20 mistral_eobc_ds    = 0x47A30278 mistral_dma_register  = 0x30000000 mistral_glbl_reg   = 0x10020000   Misc.

I have a number of switches being monitored that are reports many outdiscards on various ports. What is the easiest way to prevent outdiscards from occurring on ethernet ports?  ... View more

So we rant into an issue today where we were hitting the limit of the number of allowed vlans on a switch (128). We are trying to find out an efficient way to determine what vlans are not needed on a switch so that we can clean them up to get us below the 128 threshhold. Being that our environment is so large doing this process by manual commneds is not ideal. I am putting this to the community in the hopes of finding someone that may have a script or other effecient process for accomplishing this. Look forward to the responses. Regards, Mark        ...

All, I got a ticket today and it was in regard to the error count on one of the TenG interfaces on one of our ASR9K's. In looking at the interface I noticed quite a few Input Errors on the port. I cleared the counters and monitored. In checking the port again I saw the Input Errors again incrementing. On the smaller Cisco switches you can ususally run the show interface gig 1/1/1 counters error command. With the ASRs you can not. I am wondering if someone could explain what the Input Errors could mean. Media issue? Incorrect Setting? Not sure what I need to be looking at being I have little time on the ASR's at this point. Thanks.           Regards, Mark        ... View more

I have a port channel setup with each of the member ports reporting various errors.  Here is what I have for each port using the show int counters errors command: Port        Align-Err     FCS-Err    Xmit-Err     Rcv-Err  UnderSize  OutDiscards Gi1/0/1             0        1582           0        1582          0      1637667 Port      Single-Col  Multi-Col   Late-Col  Excess-Col  Carri-Sen      Runts     Giants Gi1/0/1            0          0          0           0          0          0          0 Port        Align-Err     FCS-Err    Xmit-Err     Rcv-Err  UnderSize  OutDiscards Gi2/0/1             0        4456           0        4456          0      2704033 Port      Single-Col  Multi-Col   Late-Col  Excess-Col  Carri-Sen      Runts     Giants Gi2/0/1            0          0          0           0          0          0          0 This port channel is an uplink to another switch.  Can someone help me figure out what might be the issue in relation the errrors being displayed? Thanks!! ... View more

I am getting a ton of OutDiscards on both of the ports of a port-channel.  I am not sure how to resolve.  Could some provide some help?  Below is the port configs of the problem ports: interface GigabitEthernet1/0/6 description to s-sctrcr-2355-1 switchport trunk encapsulation dot1q switchport trunk allowed vlan 2-899,1100-1499,2500-3899,3969,4070-4074 switchport mode dynamic desirable logging event trunk-status logging event bundle-status logging event spanning-tree logging event status channel-group 1 mode on spanning-tree cost 20 interface GigabitEthernet2/0/6 description to switchport trunk encapsulation dot1q switchport trunk allowed vlan 2-899,1100-1499,2500-3899,3969,4070-4074 switchport mode dynamic desirable logging event trunk-status logging event bundle-status logging event spanning-tree logging event status channel-group 1 mode on Could it be just a dirty optic?  Bad cable?  Thanks in advance. ...
