On a 6500 switch running ios 12.2, is there a way of clearing all config settings for a specified interface? I want to avoid going through and having to type "no blah blah etc" for each line.

I have a cisco 800 that needs to be reset back to factory defaults. I tried typing in "config factory-default 10.10.10.1 255.255.255.0" at the conf t prompt, but I got an error Invaild input detected at ^ (the ^ is just under the word factory). So after a bit of reserch I came across this command "write erase" that seemed to do something but now I can't get any ip addreses. Here is the running config:

One one of our Cisco 6509s I've globally enabled QoS and set a port to "trust cos". However when I look at the queueing for that interface, I notice that the receive queue thresholds have not changed to the default.
I'm kind of new to QoS so I'm not sure if I'm missing something.
We are using a Cisco 6509 running 12.2(33)SXI3 using the WS-X6724-SFP card. I thought I'd be seeing the default tail-drop thresholds, but instead I still see the defaults as if QoS were not enabled:

I have a network that has a pair of 6500 switches on either end, running HSRP. In between each 6500 are two to three ruggedcom switches. They are connected to each other and the 6500's by trunk ports in a straight line. The 6500's see each other as CDP neighbors, and the 6500's can see the rugged- com as LLDP neighbors (ruggedcom only supports LLDP).
The issue is that randomly devices on the ruggedcoms will drop offline and then come back. The problem is that the devices that drop offline are all in the same VLAN, so it appears like a virus - i.e. one device drops off, then multiple. Eventually the HSRP starts flapping between the two 6500s and this causes havoc on the network.I'm almost to the point of taking a laptop and plugging it into one of the ruggedcom's to see traffic, but the issue is that the ruggedcoms are outside in cabinets that laptops shouldnt be exposed to.

[code] So can we put some ports on different switches in, let`s say vlan 50, with different ips? For example, Port 0/3 on Switch 1 and 0/8 on Switch 2, but keeping the ip of the "old" vlan? Or is it necessary to configure a specified vlan interface with ip-adress for every vlan if i want to route it?

My question is that cisco website says there are two type of cable connections for this type of config --which are --T1 CSU/DSU ConfigurationSet one CSU/DSU to clock source internal, and the other CSU/DSU to clock source line. The linecode, framing, data-coding, and timeslots must be set the same on both CSU/DSUs.Four-Wire 56k CSU/DSU Configuration For my network connection which type of config i should use??Secondly i try to connect these ports by normal crossover cable it did not work.So for this type of connection i know i need T1 cross over cable-- which has RJ 48 connections at both sides.I check cable from ebay which is RJ45 RJ48 cross over -- will this cable work in my router to router connection.

What the little green/red light is on the back upper left corner of the switch is? It inside a little mesh and I belive it says vt_fail next to it.
Had water get on our switch over the weekend and this guy goes red when I fire off on demand diagnostic, but not relevant errors in any of the logs. Haven't gotten to the point where I am putting data back on the switch yet.
On my Cisco SLM248G Switch the Back pressure and Flow control are currently disable.For the Flow control is it best to set it to enable or just Auto negotations and for the Back pressure is it ok the Enable it.This Cisco Switch has 3 servers and 15 laptop users connected to the ports.Will there be a draw back to enable these settings.

I have a ASA 5505 configured with three VLANs: Inside, Outside, and DMZ.I am running an exchange server on the Inside network and have configured NAT to allow connections to it from outside. This works fine. I can also happily connect to it using it's internal address from the inside. In the DMZ I have setup a linksys router to work as a guest wifi network. I configured the ASA to block any traffic from the DMZ to the internal network.This has been working fine for the last few weeks.Wireless users cannot access any internal resoureces, but can browse the internet etc.. etc..
My problem is that I want users to be able to connect to the wireless with smartphones, tablets etc..., if they do so, they can access the internet, but not get their email. From my (limited) understanding, the problem is that the ip address I am trying to connect to is the same ip that I am transmitting from. Is there any way to send the packets to the outside network and then loop them back to the exchange server?
I have a bunch of 3750x switches that each have a 10 gig routed link back to a central 4507 (loopback = 172.30.255.255).We carved up a /24 (of course, the /24 doesn't really exist except in our address tracking spreadsheet) into a bunch of /30's for routed WAN links and /32's for loopback addresses.We started on the low end for /30 subnets (ie 172.30.255.0/30, 172.30.255.4/30, etc.).We started at the high end for the /32 loopbacks (ie 172.30.255.255/32, 172.30.255.254/32, etc.)
Well, when I try pinging 172.30.255.255 from the access layer 3750x switches, the 3750x seems to be treating it as a broadcast ping where it lists each member that responds instead of the regular !!!!! response (this makes think something is odd with the 3750x). Of course, only one member responds (the core). But even the core seems to respond with the other end of the /30 instead of the actual /32 loopback (which makes me think something is odd in the core). I could have sworn that I've setup similar topologies without problems (ie, using 10.0.0.0/32, 10.255.255.255/32, etc as loopbacks) and as long as the mask is a /32, it should work.Also, I can ping/ssh to that loopback if my laptop is on a directly connected subnet. But I can't do it from any of the 3750x switches (which are also directly connected).I've double checked for overlapping subnets, but nope. I don't see any. Routing looks fine. The actual /32 is being propagated everywhere properly.
The following error was seen on the switch and the Diagnostic Test Loop back failed following a new WS-6748-SFP module installation.Fabric in slot 5 detected excessive flow-control on channel 3 (Module 4, fabric connection 1)
Tried Hard reset of the module and still the error persist.
We recently extended our access layer using a pair of 5ks with extenders. We have a pair of 6509s at our core and they handle the intra-VLAN routing with SVIs. I recently noticed that access hosts connected to the extenders cannot pass traffic between each other if they are in different VLANs. The strange thing is these same hosts can ping devices in other VLANs as long as the other devices are not connected to the 5k environment.
For example, consider the following hosts. Each host has their gateway set to the appropriate SVI on our core.
HostA - VLAN100 - connected to 5k extender
HostB - VLAN200 - connected to 5k extender
HostC - VLAN100 - connected to 2960 off our core
HostD - VLAN200 - connected to 2960 off our core
Each host can ping each other with the exception of HostA and HostB. As for specifics, we use HSRP (no VSS) between our cores.
When I ping between hostA and hostB, I see the egress packets on either 5k1 or 5k2. I then see ingress AND egress on Core1. There are no ingress packets on 5k1 or 5k2.The egress packets from Core1 show the correct destination MAC address of the target host. The mac address table shows the mac address on po31.
I'm having with VSS Failover. Currently I have two 6504's setup for VSS with one connection to the sup engine (10Gig__Connection) and the other connection on the Module 3 10Gig Blade and the same setup on the other 6504.My question is: If the active 6504 has a power outage or the link on the sup engine goes down, and the standby 6504 becomes active, what happens when the Failed 6504 comes back online with a higher priority and preempt set? What happens with the 6504 that took over as Active and now eeds to go back to Standby, what's required?
What I'm seeing is once the Standby took over and became Active in order for him to go back to Standby mode it's asking for a reload to take place is this NORMAL?

View 9 Replies View RelatedI have a lab setup to take my CCNA and CCNP and I'm having issues trying to get WAN connectivity back to a switch at the end of my network. My lab environment consists of 1 - 2950 switch, 1 - 2620 and 1 - 2621XM. I have 1 Ethernet connection from each router to the switch and 1 serial connection from the 2620 to the 2621XM. I have the serial interfaces in a shutdown state right now so there is no loop since I do not have Spanning tree setup on the ports on the switch yet.
Right now using the fast ethernet ports on the routers and I have no issues its when I shut down those Ethernet ports and try using the serial interfaces when I start having issues. So my network layout is Ethernet from switch port f0/4 to port f0/0 on 2620 and serial from s0/1 on the 2620 to s0/2 on the 2621XM. My 2621XM f0/1 is whats connected to the WAN and I have no issues getting to the WAN from my 2621Xm or my 2620 but when I try pinging any website or even my WAN default gateway from my switch I get nothing!
Ive also noticed that when I do a IP NAT translation (after accessing the WAN from my 2620) on my 2621XM the source IP is of my serial connection not the ip of my 2620 router? I have my default gateway on the 2620 as the the IP of my serial interface on the 2621XM and vice versa because my LAN network is 172.16.1.0 and my WAN is 172.16.9.0. I have a /31 setup between my serial connections 172.16.11.0 (s0/1) is on the 2620 and 172.16.11.1(s0/2) is on the 2621XM. I used the SDM (ver 2.5) to setup NAT to have f0/1 with Nat outside and s0/2 as Nat inside. Encapsulation is HDLC between the serial links. Ive attached the running configs of the switch and routers.
I have the Cisco Linksys EA4500 router. It was set up to use the Cisco Cloud Connect. This interface is horrible. I can be online and not access my router through ciscocloudconnect.com or 192.168.1.1 while I am on my network. How is this possible? I used to have the WRTG54 router and that interface was perfect. How can I switch back to that interface with the EA4500?Cisco Linksys really should have tested their cloud more thoroughly before rolling it out to the public.
