I have a Catalyst 4500 L3 Switch Software (cat4500e UNIVERSAL-M), Version 03.02.00.XO RELEASE SOFTWARE (fc2). So I just wanted to verify that the switch only does dot1q encapsulation because the switchport trunk encapsulation dot1q command does not work.

I'm trying to determine the interface numbering convention for ports on the supervisors. Our existing 4500E all have SUP6 modules with twin-gig converters - so I am familiar with the numbering conventions used on those supervisors.

If you have a router with multiple direct vanilla FE (non trunked) interfaces on a switch trying to send QOS tagged packets to a wifi bridge several switches away does the trunking in the switched infrastructure mess with the qos tags if no qos is configured on the switches.
Does it depend on the switch? We have new 2960's running 12.2 and a few older 2950's running 12.1
In fact i receive traffic on a one client per vlan basis (traffic is PPPoE), i receive all this traffic on a router, collecting all these vlan on a bridge where the pppoe packets are treated.When I use a transeiver to convert operator fiber arrival to my router copper media interface, i have no problem....
When I use dot1q-tunnel to make the same on my 3750, packets seems to be corrupted.I get PPPoE timeouts and packet loss, not regulary, totally stochastic...
I made dozen of tests and different settings, without success I first thougt of MTU issues. [code] I made tests with system MTU and/or system jumbo MTU above 1500, without success.I didn't found any known caveats on 3750 running Version 12.2(25r)SEE4 related to dot1q-tunnel.

encapsulation of routing protocols. Where exactly in the OSI, or TCP/IP for that matter, model does the data of the routing protocol fit into ? Is it encapsulated inside the transport layer segment payload ? So far from the I've gathered, that's where it should fit.

I have a problem accessing my wireless router through VLAN sub-interface on my Cisco 1841 router. My hardware:
Cisco Catalyst 2960 switch (192.168.100.4 /24)
Cisco Catalyst 3550 switch (192.168.100.6 /24)
Cisco 1841 router (192.168.100.7 /24)
Asus RT N66U wireless router (192.168.100.2 /24)
Here's my network topology:
I have two VLANs - 10 and 20. 2 DHCP pools are configured on 2 1841's interfaces - 192.168.1.0 /25 and 192.168.1.128/26 with default router sitting on 192.168.1.1 and 192.168.1.129 respectively. No issues with obtaining IP address from any of those pools.Laptop connects to L3 3550 switch (switchport access vlan 10), which, in turn, connects to 1841 router through trunk (with VLANs 10 and 20 allowed).3550 is connected to 2960 through trunk with VLANs 10 and 20 allowed.Wireless router is connected to 2960.I can successfully ping my wireless router and outside world from 1841 from fa0/1 interface, but not from fa0/1.10 or fa0/1.20 sub-interfaces - all packets got dropped. My laptop can obtain IP from both pools (depending on port I connect it to), but can't ping my wireless router and anything beyond it.

I dont understadn how this works but basically I have enabled dhcp or so I thought bu clients dont get a lease. The vlan does but clients connecting to the switchports attached to the vlan do not get a lease and cant connect to anything. If I static the ip or use my server to issue dhcp then it's fine still some issues since I am cluceless but I dont understand what I have to do to get dhcp to work on the fa0-3 ports.

Each 6500 has one sup720 and a 6708-10ge blade and we've established the two 10ge links between the two chassis; the first from the each chassis' sup and the second from each 6708.My question is, what happens when the supervisor fails on one of the chassis?

View 5 Replies View RelatedThe last few days I've been exploring options in getting rid of some old routers accross a wan connections. I have a cat 3560 to play with and I thought I would try and use the no switchport command test out routing with switch. I've got some type of route issue and I tried a few things which I thought would fix the issue but had no effect. I'll post the config and a few commands so you can see what the basic setup is.
Here we can see in the arp that it knows about both 10.7.1.2 (PC unable to ping 10.3.3.254) as well as 10.3.3.254 (ASA).I tried adding in a ip route of 10.7.0.0 255.255.0.0 10.3.3.110 as well as 10.3.3.254. Neither produced the results I wanted allowing 10.7.1.2 (PC) to ping the ASA (10.3.3.254). [code]
in my simple network setup, I cannot resolve DNS queries from inside my NATted network. On the router I can ping both IP-addresses and names. Ping from the local machine works for IP-Adresses but not for names. When doing nslookup, addresses are not found and a SERVFAIL message is returned. I use a Cisco ISR 861 Router to connect our local LAN to the Internet (The WAN of the 861 is connected to another DHCP/NAT-Router, which in turn connects to the ISP-Modem). Addresses in the local LAN are DHCP-distributed, the DNS-Servers from my ISP are configured on the Router and the DNS-Information is distributed correctly to my local LAN machines (as I can verify by doing nslookup on Linux).

We have two catalyst 3560 switches running c3560-ipbasek9-mz.122-58.SE2.bin They are connected using etherchannel using gi 0/21 - 24 interfaces.
on 3560-1 switch, there isn't any ip-default gateway or ip route configured. It only have 1 interface vlan configured.
on 3560-2 switch, there is ip default gateway configured along with 1 interface vlan.
What i dont understand here is that, i can reach out to other subnets from 3560-1 switch in which the routing is not enabled?

Looking for multicast over IRB interfaces. My full config below, works as expected on a Cisco 1760 router (IOS 12-4) but fails strangely on our Cisco 2800 (IOS 15-1) and Cisco 1941 G2 routers.
I use Windows 7 Enterprise and VLC 2.0.0 Two Flower as the multicast video receiver. On the 1760 router, I open VLC, request the video (rtp://@239.255.0.1:5004) and it plays flawlessly.
We have to upgrade the older outdated unsupported Cisco 1760 routers. We replace the Cisco 1760 router with a Cisco 1941 router. Configuration differs ONLY in the interface speeds; F0/0 to G0/0 and that is just bout it. Using the same Windows 7 Enterprise PC, I open VLC again and request the video -same as before; No video and no voice. We swap the 1941 out and put in the 1760 again, multicast works flawlessly. If we put the 1941 router back in, multicast fails again. We put the Cisco 2800 series router in and it also fails the same as the 1941 router.
Troubleshooting, I open VLC and request the same multicast video. On the same PC, I open Wireshark and start capturing packets, - and instantly the VLC video starts playing. I close Wireshark and the video stops. I open Wireshark and start capturing packets again and the VLC video starts playing again.
Wireshark shows the video packets are being received from the source when VLC is requesting the video. If I close VLC while Wireshark is capturing packets, Wireshark shows the video stream stops.

Incoming interface is Serial
Outgoing interface is BVI

I have a Cisco 2960S stack and I'd like to tune the timers so that packet loss is minimal if a switch fails.To simulate a failed switch I have reloaded it while running a continuous ping to a management address on the stack's SVI: [code] As I see the same results when a ping is directed through the single switch (switched), and through the firewall (routed), I'm inclined to think that this is due to the stack failover timers on the Catalyst 2960S.Is it possible to change the stack failover timers (i.e hold down, failover etc), to speed up the failover process?

I have a stack of 4 Cisco Switch 3750 (1 x WS-C3750G-24T, 2 x WS-C3750-48P and 1 x WS-C3750V2-48PS) and I want to do an firmware upgrade of this stack. Actually, all the 4 switches are at the firmware version 12.2(50) SE1 "IPBase" and I want to upgrade them to 12.2(55)SE5 IPBase. According to the release notes, all the switches in my stack are supported.
To upgrade the firmware, I use the command "archive download-sw /imageonly /overwrite tftp://IP_Address/c3750-ipbaselmk9-tar.122-55.SE5.tar" The firmware gets uploaded correctly but then I get the error message "There is insufficient space in flash: to install the required image. Clean up some old images, and try again."
When I do a "show flash", I see that the switch has 5650944 bytes free of 15998976 bytes.
How can i upgrade my switches? Is there an error in my command which I use? Do I need to add an other option?
The problem is, the switches are located in a branch office and there is no direct access to them. Everything must be done remotely.
