i have issues logging into one of our core switches.its a 6509 switch but i cannot log in remotely.when i try to console in on the console port, i cannot log in instead i get the above error message.I haven't rebooted yet but would it solve the problem as this switch is a production switch.

View 1 Replies View RelatedI feel that 3560 and 3750 perform differently with the following two commands:
srr-queue bandwidth shape 5 0 0 0
srr-queue bandwidth limit 50
On 3750, the bandwidth for queue 1 is limited to 100mbps x 50% / 5 = 10mbps
On 3560, the bandwidth for queue 1 is limited to the smaller value of BW / shape weight and BW x limit%.
Does it sound about right? is there a way to check for mls qos input queue drops? The show mls qos interface xxx stat only shows the output queue drops. Maybe for some reason the input queue never drops?
i have an 2921 connected to an Catalyst 3560. My router interface shows quite a lot of input queue drops. Load is not too much max 5/255.

I have a video feed coming into my 3570. It comes in at 5 minute input rate 18777000 bits/sec, 1695 packets/sec. However, the uplink to the router is much different, 5 minute output rate 130000 bits/sec, 28 packets/sec. I am in a lab and about ready to go into testing phase for a project when we discovered this problem, as this video feed is not veiwable on the other end.

I previously put this is the 'Video over IP' discussions group, which is not getting any response.I have a 6509 and need to configure QoS on gig line cards that have 1P3Q8T queue structure. I've already got the mls qos configured, and have the correct class maps built for Voice, Video, and Signalling.(I'm not doing autoqos). I have only four classes; voice, video, signalling, and default (best effort).I need to configure the commands on the individual gig ports for the appropriate bandwidths as shown below:
1. 300 VoIP G711 calls x 100kbs/call = 30mbs of priority queue DSCP = EF (46) CoS = 5
2. 150 Video conference calls x 1.5mbs/call = 225mbs DSCP = CS4 (32) CoS = 4
3. 450 Signalling x 13kps/call = 5.8mbs (round to 6mbs) DSCP = CS3 (24) CoS = 3
4. Default class is not marked DSCP & CoS = 0

So, I am trying to limit the bandwidth used by this vlan. The service-policy output statement works, the service-policy input statement does not. My test is to get on that vlan and go to speedtest.net. My download speeds are about 3.5Mb/s, my upload speeds are about 20Mb/s.
it has something to do with this:

View 0 Replies View RelatedVlan interface would be dropping packets on the input queue? Refer to the drops/flushes below. This is from a 6500 with a Sup720, there are a number of vlans on it. This 6500 and it's HSRP partner are exhibiting the same symptoms on all the vlans I bothered to check. This particular vlan is quite lightly used, there are only about fifteen user PC's (each with 100 Mb interfaces) on it.
There is a bit of information on input queue drops on Cisco, but this is focused on physical interfaces where I can understand some packets being dropped. I would think that Vlan interfaces would have different issues.I note the "no buffer" errors as well, that also concerns me, especially as that counter is quite close to the "flushes".

I have a question about filtering incoming bgp route updates from an internet provider. This provider sends the full internet routing table and default route and on an incoming prefix-filter on the customer switch (C6509-sup720) the default route is only accepted.What happens on the 6509 switch when the BGP peer flaps?Does it need to process all the internet routing updates, and if yes probably it cannot handle all these updates?What happens with the CEF table, will the switch install the routes first?

I'm looking for a Cisco device to run a full BGP table with a 60Mb link. And one of the main restrictions is that my traffic is almost 100% real-time (voip). So the average packet size is small. Today we own a Cisco 7204 NPE400 with 512Mb RAM. I think even though I upgrade it to a G2, due to the small average packet size, the router will be near to its limit. Maybe a Cisco 7300 NSE-150? Or should I think about a switch?
View 3 Replies View RelatedI have recently installed a Cisco 2911 ISR G2 with the default 512 Mb DRAM intending to eBGP peer. I ordered the 2GB upgrade RAM however due to time constraints on backordered parts, I fired up this router and eBGP peered without it. The Peer advertised the whole route table with 400,000+ routes. The BGP session came up then the router crashed due to not enough memory. The router disabled IP CEF due to insufficient memory. I disabled IP CEF permanently and have been running the router in this condition for 3-weeks with a stable eBGP session. This resulted in no CEF, 25% CPU during light traffic, 89% memory, and 50% CPU when traffic is around 30 Mbps through the router.
I am experiencing a hit to the throughput resulting in a lost packet and practically a brief traffic stall roughly every minute. This hit is so quick that it does not always result in packet loss and IP traffic sessions are not reset. I do see this on my live bandwidth graphs that the traffic takes a dive every so often, roughly 1-minute.
I initially thought this problem could be L2 to the upstream eBGP peer but all interfaces are clear of errors. I also thought this could be the BGP session going down, however, It is always up. I thought this could be duplex mismatch on L2, however its solid and no logs on either end. Funny thing is pinging thr router from both the LAN side and the WAN side results in the same packet lost every minute or so.
Even though the CPU and memory always stays the same at under 20-50% CPU and less than 89% memory, do you think this could be the BGP Scanner walking the routing table every minute?
I am working on a QoS design which I hope to test at some point, but at this stage its from the books.My question is how to decide which queue and threshold to use for video traffic, then lower priority traffic.I understand the shaping and sharing commands, its the queuing and threshold bit I'm not clear on.The plan is to use the priority-queue for EF marked voice, this will be policed on ingress to provide an upper limit to EF traffic levels, then my second priority traffic will be video. Which queue will get serviced first once the priority queue is empty, and how do I decide which threshold to allocate my video traffic to? The document ion is not at all clear, I want to prioritse my traffic in the following order:
1 voice, use the priority queue
2 video, this to get serviced ahead of data, after voice.
3 interactive data
4 Bulk data
5 Best effort
So Q1 settings are ignored due to priority queue. Q2 gets 70%, Q3 25% etc.Is it as simple as putting video into Q2 T1, then interactive data into Q2 T2, will Q2T1 get a higher priority over Q2 T2 once the PQ is serviced?
We currently have a site with a very simple topology that uses a 3750X switch stack for a collapsed core. Everyday, the users have a conference call and experience poor voice quality.Its not bad when users call from several conference phones, but when everyone calls in on individual phones, there is choppy and almost inaudible voice quality experienced. The voice traffic flow would be as follows: Phone <-> 3750 switch <-> Voice GW We have packet captures showing that RTP packet loss is occuring from the phone to the voice gateway, but none from the voice gateway to the phones. We also have drops in the output queues that match drops on the asics. I can reset the counters and they will be clear until the call, and then they increment significantly during the call. The voice gateway and phones are non-Cisco. The switch stack has 6 switches. We are trusting the DSCP settings on the phones. All the queue drops from the phones are usually in queues 0-3, but all drops on the voice gateway is in queue 0. Below are the QoS settings; they are mostly default and we have not changed any queuing, thresholds, or buffers. Should we specify larger buffers and threshold for a designated queue and send EF traffic to that queue?

We're having some issues with a 3560 CPE. It's uplink is a GE fiber link, customer port is FE RJ45. We see a lot of TX-frames being dropped at the FE port,but none at the GE port. Even when the customer is only at ~50Mbit/s downstream traffic. When customer sending ~50Mbit/s upstream, there are no TX- drops at the GE link. Is this a normal behaviour? From what I know the physical medium shouldn't have any inpact on this since drops occurs in the port- asic, and not in physical transmission.Do the buffer-sizes between GE and FE differ? What could we do to optimize the flow and reduce drops? QoS is set to off and no modifications on the queues have been made on the interfaces.

I've been working on breaking down and understanding the default auto qos configuration on a Cisco 3750 in the hopes of putting together a QoS strategy that will fit our environment. I'm having some difficulty understanding how the "mls qos queue-set output" syntax works.
From another post, at [URL], the author offers the following example and explanation;
mls qos queue-set output <1/2> threshold 2 400 400 100 400thresshold 1: 400%
thresshold 2: 400%
thresshold 3: 100% (implicit, not configurable)
reserved: 100%
max: 400%
However, I'm having trouble understanding what is meant. Here, it looks like it's saying, for example;
mls qos queue-set output 1 threshold 2 400 400 100 400
How come there is syntax stating "threshold 2" when in the succeeding part the 400 refers to thresshold 1 and threshold 2 again? The syntax 400 400 is, apparently, already referring to thresshold 1 and 2, no?
One one of our Cisco 6509s I've globally enabled QoS and set a port to "trust cos". However when I look at the queueing for that interface, I notice that the receive queue thresholds have not changed to the default.
I'm kind of new to QoS so I'm not sure if I'm missing something.
We are using a Cisco 6509 running 12.2(33)SXI3 using the WS-X6724-SFP card. I thought I'd be seeing the default tail-drop thresholds, but instead I still see the defaults as if QoS were not enabled:
