Cisco Switching/Routing :: 2900XL Conflicting DRAM Values
Apr 16, 2012
I have a WS- C2924C-XL switch that I would like to upgrade the IOS version on. The IOS version in question can only be installled on an 8MB version of this switch, I have tried to confirm the amount of memory present in the device but I am getting conflicting values depending on where I look.The model number would indicate that this device is a 4MB version, therefore not compatable with the upgrade.Running the show version command from the CLI shows Processor having 8192K/1024K bytes of memory.Accessing the switch via the VMS management interface displays a value of 4MB.
I am using using an old 2900XL switch which has IOS V 11 which I tried to update to IOS 12.05. I followed a cisco procedure which instructed me delete the current OS file and then upload the new one with TFTP server.
I managed to delete the file however seconds after the deletion we had a power cut so now the switch is without an OS and all of the commands that I could need to continure the IOS upgrade are not available.What can I do to update my switch now?
I try to insert a picture, to make the situation easily understandable.
The problem: After I have connected one more PC to the unmanaged switch, it cannot connect to network neither by DHCP IP, nor Static IP. (Physical Link is Ok, but no communication)
Tests made:
- PC1 turned off, to test connection, but PC2 cannot connect
- portfast has been turned off on the port of Cisco (which connects to Mediaconverter), but PC2 cannot connect
- PC2 has been reinstalled, replaced, other network adapter has been inserted, but cannot connect.
- the unmanaged switch has been replaced to a new one, but no success.
PC2 can connect to Cisco only if connected directly to RJ45 port of D-link Mediaconverter. But this is not a solution, because in that office, I would need for both of the PCs.
running config of the switch:
System image file is "flash:c2900XL-c3h2s-mz-120.5.2-XU.bin" cisco WS-C2924C-XL (PowerPC403GA) processor (revision 0x11) with 8192K/1024K byt es of memory. Model number: WS-C2924C-XL-EN #sh run Building configuration... Current configuration:
the problem shows an error in a switch catalyst 2900XL - its a 2924 -, i was copying the image of the ios via xmodem and before finished the the power energy in the facility shuts down, when the energy supply returns the switch get power energy normally but the flash memory doesn't initialized and the loader stuck when i try to initializy the flash or reset

Right now i am able to access the router . whats this error about -- is router going to crash or reboot?
The default value of DRAM and Flash memory are 128 MB and 16 MB of Cisco Catalyst WS-3750-24PS-E switch .I want to know , wherther the default value may be change upto 256 DRAM and 128 Flash.
I've been working on a 3560 that doesn't seem to map dscp values to a new value: mls qos map dscp-mutation ToR1 22 24 to 46
[Code]....
On the router on the other side, I created an acl that matched on dscp 46, but it doesn't match on it. I've tried moving the mutation map to the ingress interface and I've tried setting dscp with a service policy instead of marking COS and using internal dscp. Where is the mutation map supposed to be placed: ingress or egress? Also, I added an entry in the acl on the router to see if I was mapping to dscp 24, and I am:
[Code]....
So it seems like the mutation map is being ignored completely. Any reason why?
We have a C4500 with 2 sup V which is showing high CPU values sometimes.When this occures, the switch shows 95-100% for total cpu for a few hours at a time.show proccesses cpu shows process Cat4k Mgmt LoPri with an unusual cpu value of 65% The show platform heath command gave me a high reading for K2FibFC DelFlow which is about 50% at this peak but is normaly around 1%?
what the process K2FibFC DelFlow means and what could be the cause of this peak?
I've been having a debate with a colleague about QOS COS values. My colleague says I need to use COS values across layer 2 trunk links between access layer switches and core switches. My argument is if phones are marking packets with DSCP values I don't need to be concerned with Cos.The reason I ask is we're implementing a new phone system, the ip phones will mark RTP traffic wih dscp value EF and Call signaling with DSCP value of CS3. If my understanding is correct I can trust the dscp values of the phones. We are using Cisco 4507 switches which I believe automatically trust dscp values so I would just need a class-map to match the dscp values and apply the output policy map on the egress interfaces as follows? [code]
We have a 4500 series switch that is running around 39% cpu utilization but seems to be dragging a bit. I did a show platform health and GalChassisVp-review has a target of 3% but an actual of 17%. All other actual values were at or below target values. I then went to show platform cpu packet statistics and in the "Packets received by Packet Queue" all queue packet values at 5 sec, 1 min, 5 min and 1 hour avg were either 0 or 1 with the exception of Esmp - that averaged 351/377/317 and 313 respectively. I then checked show platform hardware acl input entries static and the entry type InputEsmpToCPU had a whopping 10121370 hit count. All other entry types were well under that number.
I have a stack of 4 Cisco WS-C2960S-48FPS-L switches running c2960s-universalk9-mz.122-58.SE1 code. One of our network monitoring tools is indicating discards on a certain port on the switch. Upon further investigation I am seeing the Total output drops values change in a very odd manner.
The numbers seem to go from 573 to 1146 to 1719 then back down to 573 and it starts the same pattern over: [code]
The port utilization is quite low, the highest I've seen over the past 7 days is 3.5% with a polling period of every 30 seconds using Statseeker. Yet the discards are bouncing all over the place.
I've searched though the bugs for 12.2(58)SE1 and didn't see anything.
What are the best values for "mac address-table aging-time" and "arp timeout" by following scenarios?:- single sg300-10 as layer3-switch with a maximum of 10 local (direct connected) hosts - and a 3750x-stack with 100 local hosts + hsrp with a other stack of the same sort or for asa 5520 as internet gateway for 500 clients?I use at the moment a mac aging-time from 300 seconds and a arp timeout from 3600 seconds.
I am using 10Gig link to connect distribution and access switches. Since we are terminating the cables at multiple locations, we are also doing the link budgeting. The CISCO SFP 10G-LR module data sheet shows two values for the transmit power one of which is maximum power .5dBm and another is minimum power -8.2 dBm. Which value should I choose for the link budgeting.
I have recently changed ISP and am now with Sky. I have been having battles with Sky over my speeds - they said I would get between 4.5/9.0MB and I have been getting just 3.6MB. However, even this lower figure has changed over the past three days and I am only getting 1.6MB on the same PC which is based upstairs. I noticed that on my laptop I was getting 3.6MB downstairs and so I took it upstairs next to my PC and then obtained 3.6MB. Is there any reason I should be logging two drastically different speeds from the same location on two separate items of equipment? I started thinking it was the Philips SNU adapter on the PC which may be causing the problem but I have tried a spare adapter(same make & model) and I still get the lower reading.
on my laptop the wireless card works fine and the usb's work fine but as soon as i plug in a usb device witht the internet connection running. it cuts of the wireless connection. and again when i refresh the wireless connection the usb device loses connection.
Been trying to config a 2924XL switch via telnet. Always within Two(2) minutes. the switch reboots and knocks the telnet session down.When I unplug the switch it will once again hookup but only for a couple of minutes.
Last month I was reviewing following Cisco document, in which Cisco mentioned that ""To avoid possible memory fragmentation in the forwarding information base (FIB), Cisco recommends that the switch processor (SP) DRAM to a minimum of 1 GB ""

Since this document has been revised in Oct 2011 and, I can't no more find the above memory recommendations.
I want know if any one using WS-SUP720-3B with IOS SXI6 and Cisco ACE30 has gone for upgrading the SP DRAM from 512MB(default) to 1GB ?
I 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 need to upgrade the active/standby failover pair of 5510 ASA's to have1 Gig DRAM each, and I am trying to plan out the upgrade process. I'm looking for a zero downtime upgrade process.
I know that the failover pair has to have the same amount of memory, so how do I perform a zero-downtime upgrade process?Can I power off the standby unit and upgrade it's memory first? Or will it cause a memory mismatch between the active and standby units when it is powered on?
I have copied status codes from show ip bg command output and its explanation (from Cisco documentation site)., d and h (suppressed, dampened and history). I read somewhere that these are to control flapping routes. But not able to understand it completly.Raised this question in a couple of forums but didnt get a proper reply.The table entry is suppressed.??The table entry is dampened. ??The table entry history. The table entry is validThe table entry is the best entry to use for that network.
Now, with all the unified communications, voice, video and data are in the same device, and I try to give priority to voice and some applications, but in the WLC I can not find the way to mark all that kind of packets.
Is it possible to do that? like in a LAN making the marking as voice, signaling and any kind of application? as I marked in all the LAN.
I am running ACS 5.2 (more detail below) eval demo version for a proof of concept and noticed an oddity.. It appears that if you create a Endstation Filter and click the CLI/DNIS tab, click Create and then click DNIS and enter your info ex: *coolssid and hit submit it shows everything correctly, but if you go back and edit it. it swaps them.
Version : 5.2.0.26Internal Build ID : B.3075.EVAL..If you have the webex recording viewer you can watch the little Webex Recording I did showing the steps and the issue.
We purchased a Cisco 541w router for one of our customers.
The main reason was to provide them with 3g backup solution for their business.
In order for the router to recognise the 3G router the firmware was upgraded SRP540_1.02.01_023_081211_1136.
We arrived on site last night to do the install but couldn't make any changes to the already configured router. Every time we attempted add a vlan or adjust the dhcp scope the router would return "The values are invalid".
Worked at this for over 1 hour and then decided to factory reset the router to see if that would revert the router to use the original firmware.
This didn't revert to the previous firmware but we magically could now make network changes without problem.
So everything was good, we reconfigured the router, tested 3G and failed the wan1 interface back and forth and the customer was very happy.
Customer arrived onsite this morning and the router was running on 3G. Every 8 - 10 minutes it was attempting a failover between connections.
I decided to turn off the failover for the time being and investigate further but yet again i was back to "the values are invalid"
We've had to pull the router as the customer is about 2hours away and revert back to their BT router.
Found this document for another SRP model - A warning message may appear in the Basic Wireless Settings screen with the text “The values are invalid” when modifying the wireless profile. Set the SRP 521W to its default setting (CSCtd49614).

Will firmware SRP540_1.2.4_003_011112_1847 released only 2 days ago cure the problem?
I have a WLC 2106 with 3 APs. Everything works and users can connect, but the throughput seem to be lower than it should (it is around 8Mbps and should be around 30-50Mbps). And all speed and duplex has been accounted for.
I am trying to understand the stats that I see for the 802.11 MAC counters I under the Wireless APs.on the controller.
That screenshot is attached. I see high numbers for the following areas:
my cisco 2611 series router is showing garbage value at start up and not allowing me to enter in Romon mode I check the bitrate in console .it is 9600/8N till then i am unable to start the router Can you tell me how to change configuration register value without entering in rommon mode
I am scanning the documentation for CPI 1.2, trying to get it to use CSACS 5.3 for my authentication/Authorization. The docs say to create a TACACS Shell Profile, and add the TACACS A/V Pairs as needed... . nowhere could I find a listing of AV Pairs I can use to grant authorization. I did see that what ever pairs I did use, I must keep the menu chain in tact..
i am searching for the right SNMP-OID to poll the values of the CPU-load from a VSS (6509E)here a OID for VSS-Switch1 and a other OID for VSS-Switch2 values like cli-command "sh proc cpu" of the supervisor-module in slot 5.
