Cisco Switching/Routing :: 2921 Interface Not Coming Up
Oct 2, 2012
I have a CISCO2921. I am not able to bring up its gi0/1 interface. It stays down down.
[URL]
I know that interface is not coming up because of "no media" below. Router#sh int gi0/1 | i media Auto Duplex, Auto Speed, media type is no media
I have tried media rj-45 and media sfp which have also not worked. The other end of this link is ethernet handoff. What is it that I have to do for the link to come up? If I change the connection to gi0/2, I think that will work because I see this for gi0/2:
Router#sh int gi0/2 | i media Auto Duplex, Auto Speed, media type is RJ45
I just finished setting up a bundle of (2) T1's in a multilink bundle and I'm having issues with one of the T1's not wanting to join the bundle.
The router I'm using on the remote office location is a 3620 router running code c3620-i-mz.121-1c.bin
The campus router which is a 7206 is setup the same exact way with multilink 240 and like I've said, serial 0/0 is joined to the bundle just fine, so we are running off one T1 connection.
The serial interface that is not working is: serial 0/1
Here is a show-run:
interface Multilink240 ip address 172.18.xxx.xxx 255.255.255.252 ip route-cache flow ip ospf network point-to-point service-policy output PhonesFirst ppp multilink
An interface on 2921 router is not coming up. When I shut/no shut the interface, I see this:
Router#sh log | i 0/2 Oct 17 08:55:06: %IP_VFR-7-FEATURE_DISABLE_IN: VFR(in) is manually disabled through CLI; VFR support for features that have internally enabled, will be made available only when VFR is enabled manually on interface GigabitEthernet0/2 Oct 17 09:00:35: %LINK-3-UPDOWN: Interface GigabitEthernet0/2, changed state to down [Code]...
why Cisco 2921 Gigaethernet 0/1 is not coming up ? I also tried to connect the interface to another SWITCH with no joy.
ME3400 (ISP's switch)<-------------MPLS link--------------> Cisco 2921 Gi0/1 >>>>>>>>>>Port not coming up
I tried connection between ME3400 (ISP's switch) and spare switch and the INTERFACE of spare switch was in UP/UP state .Troubleshooting I did so far on Interface Gi0/1
1> Changed ths speed/duplex manually and revert it back to auto
2>diable keepalive
3> Tried differnet LAN cable with no luck
4> Please see HIGHLIGHTED part (in red colour) of "Show controller Gi0/1" command
I am pasting some of the SHOW command output R2921_MMP#sh run int gi0/1Building configuration.[code]
I have hardcoded 1GB ports on 3750X to 1000 and full duplex for all servers connected. THe ports are not coming up with this speed and duplex settings. If I configure them to 100, I am able to see the port is up. Whereas if i connect the same servers to 2950 switches, i can see the ports working fine with 1000 speed ..we have tried with the latest universal IOS as well
I have 2 ASR routers running PIM-SM between them on several sub interfaces.PIM hello interval configured for 200ms.Sometimes PIM neighbors between ASR routers going down.
Reboot for each router not resolving the problem.Deleting ip pim sparse-mode and configuring it again on one of the ASR routers resolves the problem.
I didn't find any related bug.The version is asr1000rp1-adventerprisek9.03.06.01.S.152-2.S1.bin
We have recently purchased Catalyst 4510R-E with two PoE line cards. When we connected Cisco Wireless APs to Cat4510 PoE ports it did not come up. These WAPs are working fine on other Cisco switch with PoE ports so there is no issue with WAP. We have received two CAT4510 and on both two slots are populated with PoE line cards and on both switches WAPs are not coming up. PC/desktops are working fine on these ports.Is there any configuration required on Cat4510 to enable PoE feature.
Basically I have both PC's pinging 4.2.2.2 DNS, Layer 2, Layer 3 intervlan routing functioning, 2801 Nat is translating, able to ping default gateway of ISP and have configured DNS from what ISP has given under my DHCP scope, however Im still not getting, web pages opening up when i open mazzila or firefox !
I have a Cisco Catalyst 3100 blade in a Dell server chassis that is trunked to a 6509.
When doing a protocol capture, I see large frames being sent from one of the servers in the chassis.
Example:
TCP:[Continuation to #1701] [Bad CheckSum]Flags=...AP..., SrcPort=HTTP(80), DstPort=2667, PayloadLen=2831, Seq=1489611217 - 1489614048, Ack=1719592331, Win=65535 I see lengths up to 6900+ bites coming from the server.
The switch has the global MTU set to 1500
system mtu routing 1500
and I can't seem to set this at the interface level. The server is configured to send 1500 length frames. Why am I seeing these jumbos? (the server is Windows 2003)
We are trying to connect 2 nexus 5558UP (5.1.(3)N1(1)) with 10G-SFP+-LR interfaces. The interfaces are not genuine cisco's (smartoptics) but as far as we can tell, they are accepted by the hardware. If we take a look at the optical levels, we can see that the switches can see eachother (double-checked by bringing down one interface to see if optical levels really disappears) on optical level, well within limits. I found a notice about changing debounce timers but this doesn't work, setting it to 0 or 1000 doesn't make a difference. Copies of the different show int commands can be found at the end of this text.

Having a strange issue here with an 7606-s chassis equipped with two sup720's, and two regular line cards. There is only one power supply, PWR-2700-AC. I recently builded this setup and powered it on last week for the first time. It ran fine for about 20 minutes while suddenly the chassis powered down.
I've checked the back of the chassis and noticed that the power supply had it's 'input ok' and 'power fail' led lit. I toggled the power switch and waited half an hour to power it on again. This time only 1 minute of joy. My first idea was the PSU due to the power fail led so I had it swapped by the supplier for another. Unfortunately, when I powered it on today, it didn't change a thing, still unexpected power downs.
So I've checked the following documentation: [URL] and followed the suggestion to power the chassis on without any modules in the slots. So I did that and it ran for 8 minutes only. However, the fan tray did respond properly when I removed the small thermal module in the upper right by increasing the fans to full speed.
Following above documentation, it points to the chassis (there is not much left). Now the real question comes, isn't there anything else that could be the cause of this?
I 'm trying to set up a home lab with a couple of 28XX and 2651XM series routers.I would like to simulate a frame-relay connection between HQ, Branch1 and Branch2 . All of them are conneced to a PSTN switch (2811 router) via T1 cross over cables. The connectivity is like this. [code] I have configured all the routers and FR switch with necessary configuration. However the link between HQ and Branch1 is not coming up. On both the routers I could see the line protocol is down.I have pasted the configuration below.[code]
I have problem with traffic coming from GRE interface and going further through FWSM on the same 6509-E chassis.It's very interesting and confusing. If packets are fragmented, I can go through, however, if I use normal packets (usual ping for example) traffic goes from outside to inside and stops on it's way back.
Here is the detailed info: WS-C6509-E with WS-SUP720-3B FWSM HW 4.0, SW 4.1(4)
GRE is done in hardware (source is loopback interface - only one loopback per GRE tunnel).
We are in the process of switching our infrastructure of our routing/firewalls/vpns over to cisco. We are switching our first location and one of the issues I'm struggling with is windows authentication pass-through for internally hosted web pages. Meaning, user inside our network has the 2921 as their default gateway, they try to access a web page that is hosted on the internal network but is secured with windows authentication. In the past, because they are logged into the domain internally, the website authenticates and loads. After switching to the Cisco, it asks for a password even though they are logged in.
Because its the web server that actually authenticates I'm not sure why the router isn't allowing that to happen, but I can't think of anything else that could be causing this behavior.
Switch is running in layer 3 mode.How can I turn off mDNS broadcast coming from the vlan interface on the switch.Getting mDNS broadcast from switch every 5 seconds.
i have a router 2921 with the aproprieted voice card for E1 and licenses. I would like to know how to configure it for incoming and outgoing calls. I already configured the ephone and SIP phones for internal calls. now i just need to configure it for send and receive external calls.
Router: IOS: c2900-universalk9-mz.SPA.153-1.T CME: 9.1 ISP from Brazil: type: E1 signal: R2 Digital Channels: 32 Phone Number Iniital: XXXX-9250 (main) ephones-dn numbers: 9250 to 9280
We have remote office where we have 2921 router with 6 layer 2 switches. We have few servers which need to be in specific vlan.
2921 router does not have switching engine we are using this to support VOIP.
So on 2921 router i created 6 sub interfaces for each vlan and assign them to their specfic vlans. Then I have trunk connection to switch 1. Now switch 1 connects to all other switches in the network. As our company design all layer 2 switches should be transparent mode. i tested them i can ping from one switch to all other switches.
Router vtp mode i set to transparent mode and from all switches i can ping the router sub interfaces.
configuring up a 2921 router for remote site which is fitted with 24 port Etherswitch module.As part of this setup I have defined 3 vlans on the router, but when I go onto etherswitch and for example set switchport access to access vlan 3 it is not aware of this vlan.Do I have to set up trunk inbetween Router and its etherswitch?Wish I had ordered seperate switch as it would have been easier or am I missing something.sho vlan-switch shows my vlans but on swicth sho vlan brief does not.
This is for a short temporary time until I get cisco 3560s in place. I have a 2921 configured and it is connecting to an HP non managed non VLAN switch and I cant get any traffic to pass from my computer to the router (pings or anything). Here is brief configuration that should be enough. [code]
Here are my vlans 1-default, 2-management, 192-data, 92-voice, i believe its running rapid spanning tree protocol. Do i have to take off encapsulation on my data vlan to get it to work or make the data vlan default vlan for everything. I am lost as to why this is not working.
I have a 2921, and I have 4 network segments. In segment 172.16.0.0./27 I wand to "pair" somehow connections. I mean IP 172.16.0.x has to have MAC aaaa.bbbb.cccc and so on, and not accept connections otherwise.How can I do that?
I have a 2921 with 4 segments: [code] My DHCP server is 172.16.5.2 and I need to serve clients from 172.16.2.0/23 by MAC address and only to that segment.
What I’m looking to do is setup a net-flow monitor for traffic going across a PIX firewall. I know unfortunately I can’t do this directly from the PIX because it does not support net-flow.
I do have a 2921 router on the same network that I have net-flow enabled to monitor traffic across the MPLS Connection.
Since the traffic for the MPLS is going out a direct interface I have applied the IP Flow egress/ingress commands to that interface to obtain the net-flow data I need. The PIX firewall however is not a direct interface so this can’t be done. I have done a little reading and believe I could use a policy map to create a “filter” so that any traffic that meets the ACL associated with the Policy-Map would get sent to net-flow monitor.
My question is how do I set that up so that so I can have the two net-flow data “streams/sources” go to separate net-flow ports so that I can monitor them independently of each other or is that not possible?
Both devices are connected to a 3750X switch; however neither is connected to a 10GB port. To my understanding that means I can’t run net-flow on the switch itself.
got a RPS2300 with 4 cat3750g48ts on it (yeh I know - Cisco documentation allows only 2 of them ). What will happen if I connect an additional Cisco 2921 router?
I have a 2921 where I am shaping some traffic based on sub net on my lan. I have applied the shaping policy to the lan interface in the outgoing direction.
Topology is as follows: ISP - ASA - ROUTER - LAN Policy map: Policy Map shape-lan [code]....
I am seeing a lot of no-buffer drops on the policy and I am wondering what the best solution is to solve this: Class-map: tc-class (match-any) 8730680 packets, 10803689863 bytes 5 minute offered rate 4453000 bps, drop rate 0 bps [code]....
Should I just be increasing the queue-limit or should I be changing something else?
I have a 2921 router and want to use mpls feature. Right Now we are using c2900-universalk9-mz.SPA.151-4.M1 image but mpls static cross connect” is not working with this image. And will this image(c2900-universalk9-mz.SSA) be worked?
I can not find any information about management port of Cisco ISR 2911, 2921 and so on. There is management port in specification of 2911 and 2921 and I do not know if this port can be as a simple Ethernet port – forward traffic in/out on L3.
the cisco 2921 Router has a default ip hhtp access class command found in it. Just i changed the default IP to the new ip i will use.The Router is accessable from the LAN only but not from the internet configured the Public ip . I think this is due to the standard access list 23 . how will i access the Router from the Internet using the Public IP.
I have 2 links to 2 different departments switch with an up link of 10mb. I want to guarantee that both departments get at least 5mb, but can use part of the other 5mb that not in use. Is this possible?
