hi, i've received a mix of plastic (bright yellow) and metal (gold) GE T SFPs and used them on ASR1001-x. the 'CISCO' SFP on ASR-2 works perfect but i got the link between ASR-1 and N3K switch UP using 'CISCO-METHODE' after hardcoding negotation, speed, and duplex settings BUT getting a very small increment CRC errors on the N3K side. there's no CRC errors on the ASR1side   ASR-1#sh int g0/0/1 GigabitEthernet0/0/1 is up, line protocol is up   Hardware is BUILT-IN-2T+6X1GE, address is 00fc.bab6.1234 (bia 00fc.bab6.1234)   Description: Eth1/11   Internet address is 1.2.3.4/27   MTU 1500 bytes, BW 100000 Kbit/sec, DLY 10 usec,      reliability 255/255, txload 157/255, rxload 158/255   Encapsulation ARPA, loopback not set   Keepalive not supported   Full Duplex, 1000Mbps, link type is force-up, media type is T   output flow-control is on, input flow-control is on   ARP type: ARPA, ARP Timeout 04:00:00   Last input 00:00:00, output 00:00:03, output hang never   Last clearing of "show interface" counters 3w0d   Input queue: 0/375/0/0 (size/max/drops/flushes); Total output drops: 0   Queueing strategy: fifo   Output queue: 0/40 (size/max)   30 second input rate 61984000 bits/sec, 13460 packets/sec   30 second output rate 61955000 bits/sec, 13435 packets/sec      462652296 packets input, 254086241871 bytes, 0 no buffer      Received 11533 broadcasts (0 IP multicasts)      0 runts, 0 giants, 0 throttles      0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored      0 watchdog, 110382 multicast, 0 pause input      460940740 packets output, 253736175337 bytes, 0 underruns      0 output errors, 0 collisions, 2 interface resets      2260 unknown protocol drops      0 babbles, 0 late collision, 0 deferred      0 lost carrier, 0 no carrier, 0 pause output   N3K-1# sh int e1/11 Ethernet1/11 is up  Dedicated Interface   Hardware: 10/100/1000 Ethernet, address: e4c7.22c0.1234 (bia e4c7.22c0.1234)   Description: ASR1   MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec   reliability 255/255, txload 1/255, rxload 1/255   Encapsulation ARPA   Port mode is access   full-duplex, 1000 Mb/s   Beacon is turned off   Input flow-control is off, output flow-control is off   Switchport monitor is off   EtherType is 0x8100   Last link flapped 11:50:25   Last clearing of "show interface" counters 02:04:28   0 interface resets   30 seconds input rate 53631800 bits/sec, 12170 packets/sec   30 seconds output rate 53666984 bits/sec, 12201 packets/sec   Load-Interval #2: 5 minute (300 seconds)     input rate 51.96 Mbps, 11.87 Kpps; output rate 51.99 Mbps, 11.90 Kpps   RX     93094489 unicast packets  8285 multicast packets  3110 broadcast packets     93105996 input packets  50908204410 bytes     0 jumbo packets  0 storm suppression bytes     0 runts  0 giants  112 CRC  0 no buffer     112 input error  0 short frame  0 overrun   0 underrun  0 ignored     0 watchdog  0 bad etype drop  0 bad proto drop  0 if down drop     0 input with dribble  0 input discard     0 Rx pause   TX     93284129 unicast packets  18482 multicast packets  1818 broadcast packets     93304429 output packets  50937193987 bytes     0 jumbo packets     0 output errors  0 collision  0 deferred  0 late collision     0 lost carrier  0 no carrier  0 babble 0 output discard     0 Tx pause     i'm unable to remove the SFP since it's in a production and only able to issue 'sh hw-module transceiver' commands. cable and SFP were already swapped and suspect i got a bad batch of SFP or third party ones.   can someone advise if there's compatibility issue on GE T SFP between ASR and N3K? is CISCO-METHODE a non-genuine SFP? how can i tell without removing from the chassis? any other show commads i can use?   ASR-1#sh hw-module int g0/0/1 transceiver idprom brief IDPROM for transceiver GigabitEthernet0/0/1:   Description                               = SFP or SFP+ optics (type 3)   Transceiver Type:                         = GE T (26)   Product Identifier (PID)                  = SP7041-E          Vendor Revision                           = E     Serial Number (SN)                        = MTC18291234      Vendor Name                               = CISCO-METHODE     Vendor OUI (IEEE company ID)              = 00.00.00 (0)   CLEI code                                 = N/A         Cisco part number                         = N/A         Device State                              = Enabled.   Date code (yy/mm/dd)                      = 14/07/21   Connector type                            = Unknown.   Encoding                                  = 8B10B                                               NRZ   Nominal bitrate                           = GE (1300 Mbits/s)   Minimum bit rate as % of nominal bit rate = not specified   Maximum bit rate as % of nominal bit rate = not specified     ASR-2#sh hw-module int g0/0/1 transceiver idprom brief IDPROM for transceiver GigabitEthernet0/0/1:   Description                               = SFP or SFP+ optics (type 3)   Transceiver Type:                         = GE T (26)   Product Identifier (PID)                  = SP7041-TE         Vendor Revision                           = A1    Serial Number (SN)                        = MTC21214567     Vendor Name                               = CISCO             Vendor OUI (IEEE company ID)              = 00.17.05 (5893)   CLEI code                                 = CMUIAGBCAA   Cisco part number                         = 30-1475-01   Device State                              = Enabled.   Date code (yy/mm/dd)                      = 17/06/07   Connector type                            = Unknown.   Encoding                                  = 8B10B                                               NRZ   Nominal bitrate                           = GE (1300 Mbits/s)   Minimum bit rate as % of nominal bit rate = not specified   Maximum bit rate as % of nominal bit rate = not specified ...

hi, i plan to upgrade an ASA 5525-X 8.6 code to 9.8. so upgrade path: 8.6 > 9.0 > 9.8 i've already FTP the 9.0 image on the ASA but when I FTP 9.8 i'm getting an error "No Cfg structure found" per my google search, i need to upgrade and boot to 9.0 code first. also FTP transfer takes a long time due to geo location of the FTP server and ASA. so there's a time constraint on my change window. my question is, is there a way to 'trick' the FTP let's say rename the image file to FILE.bin so it would be accepted?   copy ftp://ftpuser:ftpuser@192.168.1.1/asa982-35-smp-k8.bin flash !! No Cfg structure found in downloaded image file ... View more
