Cisco WAN :: 3845 / GigabitEthernet Port Status Up And Protocol Is Down?
Oct 25, 2011
Is the subject line status correct? I have a gigabitethernet port (3845) that went from admin down, to reset and then status Down, protocol Down. Then I had another gigabitethernt port on a different 3845 router. To show port in status of UP and protocol Down, I didn't see a reset occur on this port. Which status is correct and does the reset step affect the final status being different?
I faced a strage issue as one of our router port cable was removed from the router port but the Port status is showing as up /up which made our HSRP state to active active causing an outage , The router we are usign is cisco 3845 and IOS is c3845-adventerprisek9-mz.124-8b.bin
I have a 3845 router. Setup SSH Version 2generated rsa keys (1024)set login localtransport input ssh and telnet is enabled since I can't get ssh connection working When I connect using SSH, I get the following error. server refused authentication protocol.
Does Cisco 3750 ip sla can monitor, let's say, monitor 3750 G1/0/1 port status, once it is down, then 3750 also make G1/0/2 also down. If yes, what is the command to do it?
OK, so just mooching around in the pages of my switch, a 24 port switch and it has in the logs:
268InfoMay 15 22:43:51NIMInterface 26 is Link Down 269InfoMay 15 22:43:51NIMInterface 26 is Link Down 270InfoMay 15 22:43:51NIMevent(39),intf(26),component(2), on non-existent interface
Now, correct me if I`m wrong but my switch only has 24 ports and two of those (23 and 24) are dual personality jobbies!?Where the hell is port 26? Where did it come from? and why did it need to show up only for the switch to realise that it doesn`t really exist?
I have configured SPAN in cisco 3750 switch as below mentioned. but the destination port protocol is down.switch(config)#monitor session 1 source interface gigabitethernet1/0/1switch(config)#monitor session 1 destination interface gigabitethernet1/0/11 ingress vlan 1
We have cisco 7600 Router with 76-ES+XT-4TG3C Module connected. The Module is getting detected after upgrading the Router with SRD5 IOS.Below are the testing which we have done on the Router but we are facing the issue while configuring the Transport mode LAN and Transport Mode WAN:Brief about this is:- 2 Cisco 7606-s Router with Module 76-ES+XT-4TG3C each.- two ports on 7606-s Ten2/1 & Ten2/2 are configured as a Transport mode WAN while Ten2/3 & Ten2/4 are configured as Transport mode LAN.- We connect Fiber Cable from LAN Port to MUX and from MUX to 2nd LAN Port of the same Router. Same thing we tested by using the WAN Port-MUX-WAN Port connection.- Now on MUX end LAN port, connected Single and Multi mode fiber and on 7606 end 2/4 port which is configured as transport mode LAN, using Multimode SFP module -> XFP-10G-MM-SR, port did not came up then replaced 2/4 port with single mode SFP ->XFP-10GLR-OC192SR port came up. this is testing for LAN.- For WAN testing on MUX end used WAN port and on 7606 end checked with single mode and multimode fiber and with single XFP-10GLR-OC192SR / mulimode XFP-10G-MM-SR SFP, port did not come up.Wanted to know 1) If we have to go for Transport Mode LAN then which SFP/XSFP Module should go with along with the Single/Multimode Fiber.2) If we have to go for Transport Mode WAN then which SFP/XSFP Module should go with along with the Single/Multimode Fiber.Anything else is required while configuring the Transport Mode WAN as this is for Packet-Over_SONET/SDH? 3) MUX Side change is required while connecting both of this Modes on Cisco 7600 Router.4) Is hardware of the Router is giving any issue? Though we tested by connecting Back to Back LAN Port as well as Back to Back WAN Port. In both the situation the Ports are coming UP.
I just installed a HWIC-2T in a Cis co 3845 running IOS 15.1(3) T New build.The IOS self installed the port configuration including the command line "clock rate 2000000." I can edit everything but that entry using the CLI. When I enter the "no clock rate" it will not take in the running conf.
I am using cisco 1941 router in my DC for Internet service. I am going to terminate 2 WAN links each 4 mbps to my Gigabiethernet ports. Is bundling is possible to enjoy full 8 mbps internet to my organisation?
We have two 6509 switches with one WS-X6704-10GE module in each of them. There is an optical cable between the two switches plugged in WS-X6704-10GE module on both sides. When you shut down the port on one side the other port still stays as up and you need phisycally to unplug the cable to have it down. The same behaviour is seen no matter on which of the two switches you shut down the port, the opposite one always stays as up and only removal of the cable makes it go down.
The ports are configured quite simply:
interface TenGigabitEthernet1/1 switchport switchport trunk encapsulation dot1q switchport trunk allowed vlan 1-10 no ip address udld port
I have 3845 Router with HWIC-4ESW & I am trying to apply MQC on SVI interface but I keep getting configuration Error!-RTR(config-if)#service-policy output XYZ_WAN_QOS Configuration failed I believe that HWIC-4ESW is Layer 2 port & you can not apply Module Qos on SVI interface. I am exploring other option.
I have following link for 1 OR 2 Port Fast Ethernet port but not sure whether this will support what I am looking for.[URL] Aslo I have HWIC-1GE-SFP card on Same router where MQC works fine .interface GigabitEthernet0/1 description METRO-E duplex auto speed auto media-type rj45 service-policy output Metro-E?
I have a Cisco catalyst 2950 and would like it's basic setup. It is connected to a Cisco ASA5510 on GigabitEthernet0/1. The ASA has two v lans configured. 101 and 102. I would like to configure my switch to be managed on the following IP which is on the 102 sub net:
172.16.102.253/24
Also, i would like to configure GigabitEthernet0/1 as a runk port to allow both v lans.
I'm trying to configure the GigabitEthernet interface of the WS-C2960 switch to have a full duplex. Unfortunately, there is no option to configure this neither is the speed of that interface. But these options are present in FastEthernet ports. Is there a bug in SW version 12.2(35)SE5 that explains this abnormality?
Is there any physical or technical diferrences between PWR-3845 AC/2 and PWR-3845 AC? We are trying to order replacement parts and wondering if PWR-3845 AC is for one power supply and AC/2 means you get two with one order?

I have a collapsed core design with routed ports between all components. Access layer switches, data center switches, core/aggregation. All routed (no spanning-tree at all).Now...I have to add an IBM BladeCenter with a BNT layer 3 switch to my topology. However, those nasties don't seem to support routed ports.How can I have a routed port on my cisco switch and a standard access port on the BNT and still establish an adjacency with an SVI? I am running OSPF, but I am labbing this in my home lab with 2 x 3550s and EIGRP.

I have a 2801 router. The Fa0/0 int shows up/down. I have plugged it into diffrent cisco and non cisco switches and even a cross over cable to my laptop. I cant seem to get the protocol up. I have changed the speed to 100 and duplex to full to try to get it up that way and nothing. [code]
I was working on a problem the other day and came across something that I had seen before but never given much thought. I had a router with a switch connected to it and the interface was showing as Ethernet0 is up, line protocol is down. The problem in the end turned out to be a cable that had fell out because it was not connected correctly, but I was able to replicate this interface status on a router (FastEthernet0/0 is up, line protocol is down), and NO cable was attached to the interface.I've had a look on the internet but cant seem to find a good answer, so does anybody else know why this status is shown on the router? Remember, NO cable is connected to the interface so it isn't a speed or duplex problem
I'm looking to make a possible configuration for a customer. They need a device to provide :- firewalling- bandwidth limiting based on protocols, IP, users- web content filtering- good reporting to see which device/users are consuming most of the bandwidth.I used to use cisco ASA as firewall but it's a while I last installed on and I'm nt uptodate which current state.So I thought of using an ASA 5512-X but I'd like to know if it comply with all the requirements .Most important being the reporting and bandwidth limiting capability. It would be great to have some configuration example regarding bandwidth management.
how to bring this interface back up? It's a 1252 with 80211.n.I started configuring it with CLI and then was using the web interface. I made a change on the web interface and it caused the AP to hang. I rebooted it and can access via Hyperterminal, but I cannot ping the IP address nor bring it up in the web interface any longer.I tried the "No shut" command in the BVI1 interface.
I am currently configuring a number of cisco 2811 routers that require the BGP exterior routing protocol, however the IOS version (12.4) currently installed does not support the bgp protocol.After entering the commands into the cisco CLI 'protocol not in this image' is returned.
I have a Pix 515E running PixOS version 8.0.4 with two interfaces, inside and outside.On the inside interface, I have a Redhat Enterprise Linux 5.4 64 bits machine as an NFS server version 4 (NFSv4).On the outside interface, I have three (3) Redhat Enterprise Linux 5.4 64 bits as NFS clients.I am looking for the exact UDP and TCP ports to be added to the ACL in order to accomplish
My ISP is going to provide internet with dual path , for auto changover he (isp it admin) is planing for bgp implimentation.
is 1941 is supportable for bgp protocol ? Is it possible to create bandwitdh rate limit based on ip address on access list (be cause we are getting some 10 Ip address from isp , out of 10 ip address , 3 ip addres has to go 3 diffrent departments) , i want restrict theese 3 ip address with 1 mb traffic as 1:1.
I am using the Self RADIUS server in my Cisco ACS SE 4.2 appliance S. I have an AAA client C that interacts with S by means of the RADIUS protocol. This works fine, in that S correctly carries out authentication chores on username/password (PAP and CHAP) pairs received from C, sending back to C the corresponding Access-Accept packet when the authentication succeeds, or Access-Reject when it doesn't.
I have been able to import a set of three VSAs into S. Each of those attributes is of string type. I then configured in S a single user U with password P so that, whenever a U/P pair received in S from C is authenticated by S, S should send back to C, in the Access-Accept packet, the three attributes with the following values: [code]
With this setup, when an authentication is successfully completed by S, C receives 53 bytes worth of data from S every time. I am attaching a typical example, already disassembled. I have disguised the actual vendor ID, for legal reasons, but the rest is exactly as it was when received in C.
According to the disassembly, what we got is an Access-Accept packet, as expected. Its length is 53 bytes - again as expected, for this is the only packet that C has received from S here. However, the packet is incomplete, for attribute #3 is missing its value field.
Looking into the whole packet in more detail, it can be seen that while the wire format for the first attribute, namely, Frame-IP-Address, is correctly constructed, the remaining are not. For example, the sequence of bytes corresponding to the attribute #1 reads 1a 09 00 00 xx xx 2c 61 62 63. I believe that this is incorrect; it should be 1a 0a 00 00 xx xx 2c 61 62 63, for the wire format for this attribute consists of 10, not 9, bytes. I tried a few variations on the values for the attributes, and the results are always substantially the same, in that the wire formats for these attributes are always incorrect.
This all probably implies I have done something wrong when importing the VSAs into S, and/or when configuring things on S. I am therefore attaching the csv files I used to import my VSAs into S; as before, names and vendor ID are disguised, but their lengths are exactly the same as in the undisguised file. I used two csv files: One to import the vendor ID, and the other to import the VSAs under that vendor ID. As for user U, in S's administration GUI I clicked on User Setup and selected user U, moved to the bottom of the screen, where the attributes for this particular vendor were present,introduced the values for each attribute mentioned above, and made sure that button in front of each attribute was ticked.
