Cisco Infrastructure :: Can't Upload By Tftp On Any Catalyst 2960
Dec 17, 2012
i have few catalyst switches (2960, 3750) and i can't upload to them any files by tftp from my laptop, but i can download from them, and this bug don't appears on two routers.I was change tftp server, type of connection (wifi, cable), turn off firewall on win7, but no dice.
I have WLC 5508 in my office and i am asked to backup file configuration from WLC but when i remote WLC to get the upload configuration file via tftp it doesn't work.
But when I try to use direct connection ( point to point ) with WLC and my laptop i can get the upload configuration file. is there something wrong, actually i have connected with that WLC i can ping and telnet that device
I have a Cisco 831 router (c831-k9o3y6-mz.124-5c.bin) that cannot backup the config to a local tftp server. I have seen this behavior on a few different Cisco devices over the years and have never found a solution. The connection is made to the tftp server (in this case tftpd but similar behavior on any tftp server) and a blank file is created on the target machine file system, but the data is never transferred.
The router shows %Error opening tftp://192.168.0.2/router-confg (Timed out) [Failed] The tftpd log shows 5 repeated attempts at the file write.
Connection received from 192.168.0.1 on port 53570 [25/05 11:56:40.922] Write request for file <router-confg>. Mode octet [25/05 11:56:40.922] Using local port 61607 [25/05 11:56:40.922] <router-confg>: rcvd 0 blk, 0 bytes in 3 s. 0 blk resent [25/05 11:56:43.922] Connection received from 192.168.0.1 on port 53570 [25/05 11:56:43.923]
[Code]...
This is also stopping me upgrading the image on the router as I cannot transfer in the other direction either.
> ARP failed with failure code 1. TFTP transfer aborted.
I connected cross cable between router and my pc and i put image of router in tftp_file with tftp server so when the router wants confirm y or n and i make y so my connection area connect and disconnect and never make connection with router so how can i slove it what are the steps in my pc and the router i used solarwinds tftp server ...
I am doing image upgrade on Catalyst 6509-E. During TFTP image transfer to sup-bootflash I always see !!!!!!!!!!!!!!!!!o!!!!!!!!!! "o" out of sequence packet. Although the image size seems to be correct at the end but there is always some "o" packets.
I am assuming not, but I haven't tried loading with the image after seeing this.
I have windows server 2008r2 running a FTP server, so I can back up my configs and upgrade IOS when needed. My problem is than I can backup to the server just fine but when i try and restore a config or pull a new IOS over it gives me this error
%Error opening ftp://13****** (Protocol error) this is happening on every switch I have and I can't figure it out.
I want upgrade my switches 2960-24PC-L RAM: 128MB and Flash: 28MB, but in the web page of cisco I see that the requirement of hardware is RAM: 128MB and Flash: 32MB.
I download the IOS file and this file is only 11.2MB so my question is if I can upgrade the IOS because my flash is enough for upload the IOS file.
I am using Cisco 2960 access switches and dont have NTP server so i can manually set time on switches but problem raised when these switches restart they show their factory default time.
I'm running PI 1.2.1.012 and I'm having issues populating client information. Most of my switches are 2960 series. Specifically I get a lot of MAC Address "Unknown" and nothing in the IP address field. I probably get about 25% of the correct MAC address and 10% of the IP addresses. I also run CiscoWorks Prime LMS 4.3.2. and the user tracking information is about 98% correct pertaining to MAC address and IP address. My other network management tools also are very accurate.
The switches see very few traffic (under 40MB on all interfaces, summed, so far), however, I/O memory utilization is about 80% as can be seen from the show memory command:
The memory allocated is almost all Packet Data, by init, "sho memory io dead" returns zero, the memory usage seems constant, there are no errors on the log, the switches operate correctly, no packet has ever been dropped, CPU usage is about 4%.
Here I showed info for one switch, the other is in the same situation. I just want to know if this behavior is expected, I don't want to find out problems when the switches will be in production whit real traffic.
I have a Catalyst 4006 with Supervisor II engine. I have 48 port 10/100/1000 blades installed in it for connection to my servers. I am having a lot of problems with performance when connecting servers that are using 100 MB NICs. The speed of the connection is really bad. I have attempted setting the ports and NICs to 100MB Full duplex instead of auto-detect, but still get the same results.
I also have a 10/100 quad-port card installed in a NetApp filer. All four ports are trunked together and connect to 4 ports in the Catalyst. The ports in the Catalyst are trunked using the Port Channel feature of the CatOS. When I look at the port statistics on 3 of the 4 ports from the quad-card, there are a ton of runts and errors (both transmit and receive). The 4th port is fine, no errors.
I need to configure on a cisco catalyst 6509 two VACL. On cisco 6509 there are already two SPAN ports configured, there are problems configuring other two VACL?
These VACLs send traffic to a Traffic Analyzer (SIEM), there are particular configurations to facilitate the operation?
How I can prioritize Web Ex, Skype and some two websites on Cisco equipment. My set up is such that my 512kbps link goes to a Cisco 1941 router>Cisco ASA 5505>Cisco Catalyst Switch 2960>Computer.I want to be able to prioritize this on my network and test that it actually works.
We have the next Settings in our SW. We crate an ACL and aplied to a SVI for Incomming Traffic, I understand that is not necesasry to allow the returning traffic in ACL, but we can't access to rdp for example when we add the ACL, if we remove it, the acces is ok, buet when we add again the access is deny, even we have a log entry, and the ACL i just for Incomming traffic. There is no another ACL.
I've just made a purchase for a Cisco 2960 8 port switch ( Exact model: WS-C2960PD-8TT-L ), I reckon this is what I need to set up my network, so far I've gone through the Express Set-up and configured it through there with no problems. I've set up the hardware in the following manner:
-Internet Modem >Port 8 on Switch ->Port 1 on Switch goes to 1252 Cisco AP ->Port 2 on Switch goes to Linksys VOIP home Router
I let it start up and can connect to the internet through the AP, and through the router. (I'm posting through the AP-Switch set-up right now.) However, once I connect to the AP with a second client. It refuses to let the second client connect/not give an internet connection, as it would a direct connection to the modem.I'm going to assume this is due to NAT not being configured through the command line on the switch yet.
I would like to get the temperature status from this 2960 switch (and several other models. Normally this OID should be:.1.3.6.1.4.1.9.9.13.1.3.1.6 But it does not return anything.
The termperature status can be found from the command line by running:"sh env temp" This reports back ok, so I assume there is a temperate gauge in the switch.
This oid is part of the "CISCO-ENVMON-MIB" mib and accouding to the Cisco MIB selector it is supported on my switch and IOS - 12.2(25).
(Another thing I woudl like to monitor and should be supported is the fan status oid (.1.3.6.1.4.1.9.9.13.1.4.1.3). That doesn't return anything either.
What do I need to do to get the temperature environment status from SNMP query?
I have set up an ACL on my 3750 switch to deny icmp from PC A on our inside network to PC B on a different VLAN on our inside network using the following ACLs:
These ACLs belong to an access-list that also limits ip traffic to a few specific machines.When I try pinging from PC A I receive a reply message back from PC B. Shouldn't this configuration block any ICMP from PC A to PC B and from PC B to PC A? I would have expected the first ACL statement to block any packets associated with ICMP and when that didn't work I tried the second configuration.
IGMP Snooping configuration for Multicasting on Cisco Catalyst 3020
Our switch model is "Cisco Catalyst Blade Switch 3020 for HP" We are building HA (High Availability) Databases infrastructure. Currently, there are two nodes(hosts- servers) and two above switch for HA.
Oracle said we need to turn off the IGMP Snooping in order to use the multicasting for their interconnect communication. So my question is:
Q1> Is there any way to use Multicasting without turning off IGMP Snooping on Switch side?
Q2> If 'yes', how can we configure the switch for Multicasting ?
Oracle uses 230.0.1.0 & 224.0.0.251 IPs with 42000 range port for Multicasting communication.
I'm working with two Catalyst 2960 switches and I would like to know if there is a way to monitor bandwidth on individual ports. Ideally I would like to have one graph showing a bandwidth usage reading on each port. I tried using the Network Assistant to accomplish this, but I was only able to view one port at a time. I also tried using a traffic graphing program from Paessler, but a MIB file is needed to allow the program to connect to the switch. When I ran a search on the network management page the 2960 was not on the list for MIB supported products. Is this type of graph possible to do?
I have a problem with radius authentication on catalyst 2960 with freeradius as radius-server. The Catalyst is behind a HP5412zl layer3-switch. The rest of the network are hp-layer2 switches, which do radius authentication to the same radius server. The ios on the catalyst is c2960-lanbasek9-mz.150-1.SE3. Apparently there are no requests made to the radius-server, since I dont see any requests coming in. Port 0/7 is voice port with laptop behind , /port 0/8 access-port with laptop directly connected.
