I remember there is one command which can tell you which memory slot has how much big memory in Cisco 2800 or 3800. But at this moment, I just couldn't recall this command. I checked "show diag" but didn't see any information about memory.
We are facing problem with cisco 6506 switch while configuring when we try to save it, we are not able to save the config, neither we are able to view running and startup config.
We recently installed Cisco 6509-E with dual Sup 720-BXL. We are using this switch on internet Edge. Internet connection is terminating on 10GIG fiber port.We do have following line cards installed.
We do have 2 GB internet pipe.We are running load test sending http port 80 request and when load reach to arround 100 to 200 mbps and connections from out side to inside 80,000 switch start reponding very very slow and start packet loss and when I try to ping from one server to second server it show normal ping but if I tried to ping gateway IP of server which is SWITCH IP it show packet loss and very high letancy.
Switch also throw message "No memory available: Update of NVRAM configuration failed"
Brand new 2960. When I plug a cable into the port, nothing happens. The port light doesn't begin negotiation or anything, it just stays dark. The cable works fine--I have it on another switchport with a crossover connector connecting to a little Cisco SOHO switch without problems.
I've done the following: switchport switchport mode trunk switchport trunk allowed vlan 1 no shutdown
In other words, I've fiddled with it. But I don't know why it doesn't light up..
I have the requirement to assign an asymmetric bandwith limit to each port on a switch (example: 4Mbps downlink, 1Mbps uplink). I've been searching and found the option to apply policers or srr-queue mechanism to achive this, however this only applies for one direction only as far as I know. Catalyst 2960 familiy is preferred, however if this is not possible, will possibly jump to the 3560X family.
I came across an interesting issue and thought I would see if anyone else has encountered it before contacting TAC.I have two Cisco Catalyst WS-4510R-E switches with a single Supervisor V module in each chassis. Both Sup cards are now running 12.2(54) SG1; ipbasek9 firmware; yes, I plan to move both switches to 15 code but that's another story. Anyways, prior to the upgrade the one switch was running 12.2 (33) code; I suspect the code was never upgraded; running ipbase non - K9 code. The other switch was running 12.2(44) with K9 prior to upgrade to 12.2(54).

How do you save the command output from the CLI to a file on flash?
With IOS, I would normally use a pipe command to redirect to tftp, but the ASA doesn't support this as far as I can tell. As a work around I was thinking I could save the output to flash and then tftp that file off the ASA.
I am trying to assign a static ip and default gateway to my LAP through the CLI, but after I reboot it, I lose the config and it reverts back to dhcp. Is there any command to save the config to the AP through the CLI? I've tried all I can think of (i.e. wr mem, copy run start, etc...) and have looked throught the available commands but cannot figure out a way to do it..
i have one Cisco 3750, am using it as Core Switch where i have 6 more access switches are connected deirectly, and we are using VLANs in our network with the IP reange of 172.16.0.0 , now we had a new Internet connection which is dedicated to Exchange Server only.So we have TWO internet connection One for internet access to all users and another one for only Exchange Server.internet connection for the users is termiated at a Cisco 1700 Series Router and Internet for Exchage Server is terminated at a Cisco ASA Firewall.Now the problem is how can i write an access list, which says that all packets from Exchange server should be routed to ASA Firewall , and all other packets shoulde route to Cisco Router.IP address os Exchange server is 172.16.2.1, 172.16.2.2.
After I added the 3rd 3750E to my stack on Sunday I can no longer save my configs with 'copy run start' or 'write mem':
#copy running-config startup-config Destination filename [startup-config]? Building configuration... nv_done: unable to open "flash:/config.text.new" nv_done: unable to open "flash:/private-config.text.new" nv_done: unable to open "flash:/multiple-fs.new"[OK]
I have a stack of 3750x switches running 15.0 (2) SE2 IOS. When I reload the switch stack, I am seeing the following message in the logs: IPv6 user port trust TCAM write failed.
I am trying to write an extended ACL for the voice vlan.My scenario is the following:I have two PBXs with two Catalyst 4505 L3 switches.The C4505 are connected trough a trunk link.I have a VTP domain configured.
Voice VLANs are Vlan 100 and Vlan 101 with networks 10.2.0.0/16 and 10.4.0.0/16 Voip telephones are communicating between them self and everything is working fine.I want to secure both voice VLANs with an ACL to allow only couple of IPs to administer the phones.The PCs are connected trough a integrated switch via VOIP telephone.Here is the sample configuration of the dhcp pool for the PC VLAN:
ip dhcp pool PCs network 10.1.0.0 255.255.0.0 default-router 10.1.1.1 dns-server 10.10.10.1 option 43 hex 010a.5369.656d.656e.7300.0000.0204.0000.0064.0000.0000.00ff
I had to implement the 43 hex option because the PCs did not get the ip from the DHCP because of the vendor specific information.The thing that worries me is will the DHCP forward the ACKs for the PCs if I implement this test ACL:
ip access-list extended VLAN100 permit ip 10.2.0.0 0.0.255.255 10.4.0.0 0.0.255.255 permit ip 10.4.0.0 0.0.255.255 10.2.0.0 0.0.255.255 permit ip 192.168.2.0 0.0.0.255 10.2.0.0 0.0.255.255 permit ip 192.168.2.0 0.0.0.255 10.4.0.0 0.0.255.255 permit udp host 0.0.0.0 eq bootpc host 255.255.255.255 eq bootps (this I am not sure do I need) permit udp host 255.255.255.255 eq bootps host 0.0.0.0 eq bootpc (also this) deny ip any any
I only want to allow the network 192.168.2.0/24 and maybe some other hosts to access the web based http gui to adiminister the IP phones.All PCs are connected trough the VOIP terminals. I do not want to deny the traffic to PCs.
I am trying to configerate static switchports on our nexus 5548 (nx-os 5.1(3)N1(1)) over snmp.The support-list url... states that the CISCO- VLAN- MEMBERSHIP- MIB is supported.I can read the information, but if i try to set vmVlan or vmVlanType i get the message: "SET failed. ("ip-address"). Information: Not Writable."I can use set_request in general (e.g. CISCO-CONFIG-COPY-MIB). how to set the vlan and vlan-type over snmp?
I have a 3845 that I am trying to configure but it won't save. It doesn't matter what i do (write mem, copy run start). No matter what, if I reload it, it wipes the config. Am I missing something, or is it just a bad memory? I don't get any errors when I save, it looks like it takes, but no dice.
I have a SG300-28P and a SF200-24P connected via LAG Group. SG300 routes. I also have 2 VC240 IP Cameras. They are connected on ports 18 and 19 on the SF300. If I lose power, reboot or anything that makes the switches restart, the configuration is not saved. I know this by the fact that after a reboot, ports 18 and 19 are placed in VLAN 4 Untagged. If I put them back in VLAN 2 Untagged, save the configuration and reboot, they are placed back in VLAN 4 Untagged.
I read something on here about firmware the other night from my iPad so today, I upgraded both switches to the latest firmware, 1.2.7.76. After the update, I could not access the IP Cams. I went back into the configuration and they were in VLAN 4 Untagged. I once again put them in VLAN 2 Untagged, saved the configuration and rebooted. They went back to VLAN 4UP.
There was previous discussion also about xml version of files or something and that a factory reset and setting the switch up from scratch would take care of it. I cannot do this, I am a seed corn salesman. Is there a simpler way? Like saving the config to TFTP and then uploading it after factory reset? There is LLDP settings for my IP Phones too that if I lost them, I would have no idea how to regenerate them to make my switch work again. Cisco tech support had issues with it when I first got them and they set it up via remote session so I am lost beyond this. I just know that I cannot keep going into the switches to change settings and not have them saved. I lose my security cameras and video recording.
According to my boss every 3 to 4 months he has to restart our 2821 with a 16-esw module installed because of a low memory issue dealing with CEF. Here is the exact error message.

Today, one of our Cisco 3750 got unmanaged from NOC, we were able to ping the switch, also, traffic was flowing fine but not able to telnet or local login.On trying to login through console following messages were coming:
%% Low on memory; try again later %% Low on memory; try again later %% Low on memory; try again later %% Low on memory; try again later %% Low on memory; try again later %% Low on memory; try again later
[code].....
We given power on reset, after which we were able to login switch again. I wanted to know the actual reason behind it and if there is any other way to recover switch other than power reset.?
I save the configuration in the ASA 5505 using write memory or using copy run start but whe i unplug the power cord and plug it back in the ASA gets its factory default configuration.. then what i do is a copy start run to get the configuration active..
have 3 Catalyst 3750 in same stack, the IOS version is 12.2(53)SE2. Today we can not telnet/ssh to this switch, but ping is ok, and switch function is ok. I try to access the console port, it show "low on memory, try again later". After I reboot the master switch in the stack, the master switch change to another switch, then I can telnet/ssh to this switch. I check the Ciscoworks server syslog report, there are many MAC address flapping error message, and I beleive the MAC address flapping occured before several weeks. ( the G2/0/15 & G3/0/15 is connect to a VMware ESX server and the EtherChannel config mismatch with this Catalyst 3750 switch ) How to mention the root cause of the "low on memory" problem and what is the abnormal memory usage ( free memory percentage below ?% )?
i have a Ws-C3550-24-Emi switch and i need to upgrade its flash memory to 32Mb. I couldn't find any documents in cisco website about the memory upgrade guideline. Possible to upgrade this switch to 32Mb? If so, what's the max of memory i can upgrade? and the part number for this type of memory?
I have a bootflash in 4507R with the size of 60MB. I upgraded the ios from cat4500-ipbasek9-mz.122-37.SG1.bin (12.8MB Size) to cat4500-entservices-mz.122-37.SG1.bin (13.8 MB SIZE) and deleted the previous IOS.But previous IOS is still getting shown in sh bootflash: command. Furthermore, dir bootflash: commands shows there is only one IOS , which is running. How I can free the space from bootflash , as I again have to upgrade the another new IOS ( of 16MB), which I tried through solarwinds tftp and couldn't upload successfully because of its limitation. Now, If I try to upload the new IOS through FTP, it gives me memory space error. How I can free the space captured by old IOS and also how I can delete the 3rd unknown entry of IOS (shown below output of commands)?
I have a 3560 connected to an edge device and I keep etting this error. I have turned off proxy arp and turned off ip cef under the interface, however I lot connectivity to the internet when I did that. I can't seem to find any documentation on this error. I understand what it means, I just don't know how to resolve the problem.
