Cisco Switching/Routing :: 877 / Show DSL Interface ATM?
Aug 30, 2010
i've got a Cisco 877 router connected to an ADSL link. i'm using the show dsl interface atm just to have a look on its performance. i've tried to search on Cisco website on how to interpret the output but a blog gave me more info [URL]. My question now is, what readings do i consider? is it on the left (ATU-R) or on the right (ATU-C)?

I have configured a vlan interface on a 3750 switch. there is aprox 4Mb active traffic flowing through the interface, but when I do a "show interface vlan (vlanid)" the output show zero bits in and zero bits out. Its a typical L3 config with one IP on the vllan interface acting as the gateway for the VLAN devices. Is this a normal behaviur ? and if so is there any way to get the traffic in/out stats. The end PC/devices are connected to this switch via an L2 TRUNK and I dont have access to the L2 switch on which the actual devices connect. so cant get the real time stats of those interfaces.

I'm troubleshooting a 3750 switch stack problem where computers are showing input and CRC errors. I'd like to be able to execute a "show interface" command that will show me only the line showing the switch port and the line showing the input errors, but so far I can't figure out a way of combining those two parameters.
If I do "show interface | include Ethernet[0-9]�" I get all the lines showing the port numbers:
GigabitEthernet1/0/1 is up, line protocol is up (connected)
GigabitEthernet1/0/2 is up, line protocol is up (connected)
GigabitEthernet1/0/3 is up, line protocol is up (connected)

I'm dealing with a 4506 switch that whn I try to apply "sh auth sess int xx" I get "Invalid Input Detected" ... Is there any way that I can get the authenticated session over a port even if I can't apply "sh auth sess int"?

I have a really weired thing happening on 6509 device with one of my customers.The device has a SUP 2 (MSFC2) with version 12.2.18SXF17B.
any VLAN interface once administratively down or simply down shows on "show interface status" output as VLAN.While it supposed to show "Routed". However once the port is up it is shows "routed" like it should.

Facing issue with 2960G switch , where its do not display "logging trap informational " in show running and show startup .where its showing all other levels from 0 to 5 and 7 after configuration and save commands. [code] after config getting saved , it do not shows in show runn or in show startup while for all other levels it do show the config lines .I tried the same on 12.55.SE release also but its same results . Is this a limitaion of this platform, is there any doc explaining the same for reference. [code]

I have a Cisco ASA 5505 and I have my internal and external interfaces configured but I currently cannot ping from the inside to an IP Address on the outside. I had this setup and working and I have another set of equirement that I am replacing that is working with my service provider so I know it is a configuration issue. When I ping 4.2.2.2 for example I get:
Destination host unreachable
Do I need to add a static route from my inside interface to my outside interfaces?

Is there a way I can check the version of each device on two Cisco 6509 if they are Virtually connected (VSS)? When I enter the command show version, it only shows one result, unlike show module, you have an option to choose which switch by entering 1 or 2.

For an assignment in a class I am taking I created a simple network using GNS3 and set up static routing. Everything works fine, I can ping all of the hosts. One of the questions I am supposed to fill out is what happens when I use the "show ip route" and "show ip protocols" commands. When I use "show ip route" I get what seems to be the correct output. However when I use the "show ip protocols" command nothing happens. No output, no error, no nothing. It just goes right back to the prompt. This happens exactly the same on both routers in my network. incase it matters the router is c3640.
PS. would the output be non-existent because I have not set up any ip protocols. In a similar assignment I set up rip and when I used "show ip protocols" i did get what appeared to be the correct output. However I didn't write it down and when I put in the command again about an hour later after I took a break I also did not get an output until I re-entered the rip related commands.

Configuring FWSM in a 6509. When I set "firewall vlan-group 40 40-42,251", it results in: "No more than one svi is allowed. Command rejected.".
I had "firewall multiple-vlan-interfaces" set for a previous use of this module, but took that off with the "no" command. Suspect that is the issue, but do not see how to resolve. Seems similar to bug CSCsr48563, but I am at the fixed code for that bug.

I'm trying to examine the ARP table on specific phy ports on a SG300 switch. The Cisco CLI guide shows this syntax:
show arp [ip-address ip-address] [mac-address mac-address] [interface-id]
Using the CLI and the "?" key to get assistance, I'm not successful:
switch3#show arp
configuration Display ARP related configuration
ip-address Filter ARP show by IP
mac-address Filter ARP show by MAC
[Code]...
I don't have http server enabled, I prefer SSH and CLI to do my work.

how can I show the DHCP-range of a router if I don't have privilege level? (not in enable-mode),I can do a "show ip dhcp pool" - this will show me the range which is configured with the network-command.But there are also some dhcp-exclude-addresses which I can't see.... (I did a test on a router with full privilege-access)I need this because I have a router with limited access from our provider.

I am working with 3750 switch.I console the switch and turn it on and it doesn’t show text in hyper terminal with any BAUD (I tried all the speeds). The hyper terminal works with other switches so the problem is not with the hyper terminal.when I tried to break the password it stuck after I was writing "flash_init" and when I entered or typed text it show only garbage characters. I tried to break the password with all the speeds and it shows garbage output. I tried to turn on the switch and hold control + break and it showed the text only with the speed 115200, but after I left holding and tried to type it showed only garbage again. Also I tried to copy text from the notepad to the hyper terminal.

We have a number of 4507s. Most are managed via VLAN 1 address. All have multiple VLANS for traffic control. When I do a show ARP or show IP ARP the command only shows VLAN 1 info. No entries for any of the other VLANS on the switch.

I am using cisco c3660 to act as Terminal Server for the communication of production machines in my company, recently there is a communication lost issue happen and its due to physical cable unplug from the machine. to troubleshoot for this issues i have to physically go inside my production area to check on it, as i understand from vendor we can check on the physical machine to see whether the LED light on the module is green or not, but in case of need to troubleshoot at night time, its time consuming as i need to travel back to company. is there any command that i can issue in the router c3660 to check on the physical connection between c3660 router and the production machine? the IOS version is IOS (tm) 3600 Software (C3660-I-M), Version 12.1(4)

Ether channel: Cisco documents say Cisco uses proprietary hashing algorithm to compute a binary pattern that selects a link in the bundle. For example below a 2961 router with a switch module " NM-16ESW" performs" XOR" operation to compute the binary value to select a link.
R1#show ether channel load-balance Po1 ---> Source XOR Destination IP address.
1)Would you guys share the output " show ether channel load-balance" on your platforms?( i just want to see how different platform support different algorithm besides xor). Layer 3 ether channel on a sw.
On router, we first create ether channel and then assign int into port channel. Suppose we have a layer 3 switch and we want to put ports f1/1-2 in port channel 1. Can i configure like this: sw(con) int range f1/1-2 no switch port
channel-group 1 mode desirable. Or we must create a port channel just like we do on router and then assign ports to port channel?
Backbone fast: Suppose we have a switch with three ports, f1/1.f1/2.f1/3.
f1/1 ( root port)
f1/2( blocking)
f1/3 ( designated port).
Backbone fast is enabled on our network. Suppose sw receives a inferior bpdu on its current root port f1/1. Sw sends out RLQ on its designated port(f1/2) and Blocked port (f1/3). Suppose sw receives the rlq reply on its designated port ( f1/2). What will sw do? Will it expire the max-age timer on its root port ( f1/1) or will sw wait for all the rlq responses then expire the max-age timer on its root port ( f1/1) ?

I recently configured a network with a 4500 Sup7E and a 3560G with jumbo frame support. I am trying to confirm operation. On the 4500 this is straight forward using "sho int g0/nn count detail". [code] The 3560 doesn't support that command. The closest I can come to finding the number of jumbo packets is "show controllers ethernet" (example below). On the transmit side I assume that jumbo frames would be tallied in the "Too large frames" counter. The receive side is a little more ambiguous. There are 2 counters that seem to be duplicates, "Valid frames, too large" and "Valid oversize frames". In operation they are not. I am seeing the "Valid frames, too large" counter incrementing while the "Valid oversize frames" remains at zero. [code]

I have a stack of 8 3750x switches connected via Stackwise. In addition, I have these switches configured as two Powerstacks. When I look at the Powerstacks, they are showing as being in power-sharing mode. When I look at the individual switches, they show as standalone. Right now, I have 1 switch in each powerstack that has two power supplies, and then the other three have a single power supply. Below is the output for "Show stack-power detail" as well as the Powerstack configurations.

My network generally runs older routers (2600 series) with 16 port switch modules (NM-ESW-16). This has always worked great since I can configure the router and the switch ports on the fly, making changes to either as necessary. Well I am upgrading to 2811 routers, and we wanted to get gigabit ethernet ports on our switch modules. I think I made an error when I purchased a few of these switch modules: NME-16ES-1G.
The first problem, is that the switch ports don't even show up on the router config, I have to establish a session into the switch, (And I can't seem to get back to the router unless I manually switch off power and restart). I don't like this type of switch module, it's like I'm running a completely separate device, and while having a layer 3 switch is cool, It doesn't let me setup routing protocols so I don't like doing it this way. I want to go back to using a switch module that simply adds a ton of ports to my router like the NM-ESW-16. (Note: The NM-ESW-16 does actually work in the 2811 and would be perfect if it were Gigabit speed.)
The seconds problem is that the NME-16ES-1G isn't actually a Gigabit switch. It has a single gigabit port, but the 16 ports are all Fastethernet, and not gigabitethernet. So ideally, I am looking for a switch module that I can fully configure from the router interface that has 16 gigabitethernet ports, and works with a 2811. IE I want to do this. [code]

I enabled the "no service password-recovery" command on my C2960 switch. All seems to work as discribed. Only issue I have is --- which show command is used to reveal if the password-recovery feature is enabled of disabled as the command doesn't show up in the running config after you enable it ?
NOTE: The command does show up in the C2960 switch in config t mode (unlike the IOS router 2800 series), but doesn't show up in the running-config after you enable or disable it.
On the 2800 series routers (latest IOS) in config t mode the command does not show up but if you type "no service passowrd-recovery" the command function correctly and it does list it in the running configuration.
