Cisco Switching/Routing :: 6500 Packet Loss On Blade WS-X6748-GE-TX
Oct 2, 2011
we have a 6509 with ios 12.2.33SXJ
we have 2 WS-X6516-GE-TX, WS-X6516A-GBIC, and a WS-X6748-GE-TX with a WS-F6700-CFC daughtercard
our sup is a WS-SUP720-3B
we are experiencing packet loss for everything connected in the WS-X6748-GE-TX blade, right now we dont have any production device in that blade due to the packet loss we are experiencing.
this switch was running hybrid before it is now running native ios, however I can't recall if we didn't have that packet loss before. do i need to update a firmware of the card or daughtercard (if this is possible, can't say i've done it before).

We have a site were we have a 887 cisco hsiung a GRE tunnel
When pinging anything froom the tunnel source to the tunnel dest on the local lan we get a 50% packet loss
ping
Protocol [ip]:
Target IP address: 10.9.93.22
[Code].....
replicated the setup exatly in our lab and it works 100% with exactly the same config.

I have a cisco 3560E switch setup with LACP, when using LACP i receive alot of packet loss / output drops
When a ping from the server behind LACP:
--- google.com ping statistics ---
44 packets transmitted, 39 received, 11% packet loss, time 42990ms
what would cause this packet loss with lacp?
some output from the switch:
Port-channel12 is up, line protocol is up (connected)
Hardware is EtherChannel, address is d0d0.fd58.7390 (bia d0d0.fd58.7390)
Description: LACP-PORT

I have a Cisco 2960S stack and I'd like to tune the timers so that packet loss is minimal if a switch fails.To simulate a failed switch I have reloaded it while running a continuous ping to a management address on the stack's SVI: [code] As I see the same results when a ping is directed through the single switch (switched), and through the firewall (routed), I'm inclined to think that this is due to the stack failover timers on the Catalyst 2960S.Is it possible to change the stack failover timers (i.e hold down, failover etc), to speed up the failover process?

I have two 2960-s switches with GLC-FE-100FX fibre modules in and I am seeing packet loss over the link that is connected to the modules. When the interface is shutdown and brought back up it always comes up in half duplex even thought it is set to full in the config. I've seen other posts where you have to use the command no duplex then full duplex to get it to come up int full duplex. This does appear to work when I do a show int it says its full duplex however I'm stil seeing 20 - 40% packet loss on the link which suggests to me there is still a speed/duplex issue. The device at the other end is a Cisco 7200 which is set to 100Full. If I plug a Cisco 2811 into the fibre link I get zero packet loss which suggests its a problem with the switch.
I have changed the modules and fibre cables which makes no difference. As I stated at the start I have two 2960's both are showing exactly the same issue. Details of the switch are below the SFP are cisco branded:

I have been searching the message boards and wasn't having much luck. I am running some monitoring sessions on my 6509 and on the VLAN I am monitoring, I am experiencing a really large packet loss. If we hook up a laptop to the destination port and run wireshark we are seeing between 80% and 90% packet loss. I dont see the packet loss on the show port command, but I do on the show int vlan command.
The config is as follows:
Session 2
---------
Type : Local Session
Source VLANs :
RX Only : 500
[Code].....
I was doing some reading on Egress vs Ingress and I am wondering if the Egress SPAN replication state could be causing the packet loss that we are seeing or does the ingress & learn command override that?

I have a WS-X6748-GE-TX with the WS-F6700-CFC daughter card. Is it possible to replace the WS-F6700-CFC daughter card with a WS-F6K-DFC4-AXL to make this compatible with the SUP-2T? Or, are there differences between the CFC and DFC base modules?

I have a cisco 6509 switch in which i have 2 SUPs. I am using 3 Qty. of WS-X6748-GE-TX in the same switch. First 24 ports of module 1 and are not working. I replace the faulty moldule with the working one but now the new (good) module's first 12 ports stopped working. But when I insert the good card (the replaced one with the faulty) in other chassis it works fine.

We are upgrading two standalone 6509E chassis to a VSS system with new VS-S720-10G-3C cards. The 6509's have WS-X6748-GE-TX card with DFC3B daughter cards (see below). The compatablity matrix (see below) states that 67xx cards are supported but it goes on to state DFC3C or DFC3CXL cards are needed. So does this mean that the existing WS-X6748-GE-TX cards have to be upgraded or will they be supported?

I have checked server side, the bond configuration are same no changed. what is possible reason replace module will cause link offline? why "sh run all" give the port is shutdown?

If i replace a card of the same type in the same slot will I lose the configuration for that card or does it live in the backplane of the device?Is there any special command I need to run to replace the card or can i shutdown the 4507r-e and just swap out the blade?

We have 12 Catalyst Blade Switches 3020 for HP running IOS Version 12.2(55)SE. In the configuration of these switches I see the statement shown below.
no spanning-tree vlan 34,45-55,70,600,643,840,843-850
The 12 blade switches are configured as VTP clients and running VTP V2. I did not configure the statement shown above. It appered by itself. And even if I delete it, it will reapper. (The blade switches are interconnected to two 6509s. The two 6509s are the STP root and VTP bridges. I configure Vlans and STP on the 6509s).
why the statement above appers on the blade switches 3020s?
I mean I use other Cisco switches such as 3750s and 3560s and I have never seen the statement above appear by itself.

Looking at the specs for WS-X6704-10GE, it shows the port buffers at 16M per port. This doesn't seem like very much for a 10G port. Is this upgradable or related to how much RAM is in the blade?

i am implementing tcp as per rfc 793, i have one doubt, while sending first packet, if that packet lost means, tcp will wait for RTO and retransmit the first packet, and after got the ack for first packet, then only it will send second packet or without getting the ack for the first packet it will send second packet.

My workplace has a UC-540 attached to a cable modem, attached to the world wide web.
When we make VOIP outbound calls through the standard ISP, there is no auditory packet loss sympton; however, when we make calls to out sister branch through our VPN, we experience auditory packet loss symptoms.
I would think the VPN should only be affecting the encapsulation of the data. To my understanding the VPN packets and non-vpn packets all hit the router at the same time, and transport over the web in the same manner. Why would there be packet loss over only the VPN??
--Regarding QoS, if a standard layer 3 device receives a VOIP packet encapsulated in a VPN, do the QoS bits in the VOIP packet get acknowledged, or are they hidden by the VPN encapsulation?

i tried disabling the diagnostic monitor for the module, did a power enable module command and then reset it but it still fails. this is the third blade that i am replacing in a few weeks and i still get the same error. i am persuded that it is not a hardware since it is the third blade in a matter of weeks. after the module reset, i receive this error % module 3 is operationally off (FRU-power failed)
could an ios upgrade solve this issue? are there any ios related bugs?

I have a LAP-1142 connected to one of our PoE blade in our 4506 switch, it used to work fine with the following power consumption:

For about the past 2 or 3 months, I have been experiencing outbound packet loss at about the same time every evening. That timeframe is about 7 PM - 10 PM. This is most noticeable on Teamspeak 3 because of the voice disruption that other users report to me.

I have recently switch internet to Time Warner. Since the day I got it, i have experienced random packet losses of 100%. I have called time warner and they are going to send a tech out. But i would like to know more about this before he comes. I have replaced the modem with a brand new one. Surfboard SB5101N from the one i was leasing from them. They both do the same thing. I have made sure all my Drivers are up to date. I have replaced the coax cable and Ethernet cable and ran my Anti Virus and Spyware program. It does it more during online game, I have reinstalled the game and was having no problems with the ATT Dsl i had before this.
