Cisco Switching/Routing :: Possible To Mix WS-C3750V2-24PS-S And WS-C3750-24PS-S In Same Stack
Jun 14, 2011I am not on site and I have not seen a WS-C3750V2-24PS-S. Customer has a stack of 6 x WS-C3750V2-24PS-S and one unit has failed. We do not have a WS-C3750V2-24PS-S spare. Can we replace it with a standard WS-C3750-24PS-S (not V2) switch and be part ofthe stack.
1. Are there any traps gotchas?
2. What about IOS versions - aren't they different for V2 switches
3. Are the stack ports and stack cables same for both WS-C3750V2-24PS-S and WS-C3750-24PS-S
4. What is the main reason for bringing out the V2 switches. What features do they have extra?
Cisco Switching/Routing :: WS-C2960S-24PS-L Floods Network
Jan 21, 2013I have three new 2960 switches as listed in the title. I configured them as follows:
192.168.1.215 host: whse-c
192.168.1.216 host: whse-b
192.168.1.217 host: whse-a
Switches B and C flow into A before continuing on into the server room switch (distance issues).All three switches are configured for ports 21-24 at 1000 and set as cisco switches. all other ports are undefined as they have a myriad of desktops, printers and non cisco access points flowing into them. side question - should i configure them as access points where applicable even if they are non cisco? I am replacing three netgear switches that currently are in place and have no known issues other than they are old and the fans may fail soon.hooked up .217. was able to get to it from the network. Hooked up 215 and then 216. All the sudden I lost the ability to tap into the switches, any of them. (I think I had done 215 at that point too, before adding 216. I found out later it took the network to its knees as internet was lost, and the MPLS stopped functioning.
I undid the changes and put the netgears back in service and all was right with the world again. At first I thought it was a bad host name as I had used whse-a on switch C in error. I changed that after this issue.Later that day I put 215 in place. checked it from the network and could get to it just fine. Then I put 216 in service. I lost connection to 215. I could no longer get to the internet from my pc and the MPLS went down again. This time I just unhooked 216. 215 is still in place and working on the network at the moment and not causing issues. (btw these switches are not even in my path from my pc to the internet, just on the same network) tomorrow I am going to try 217 again while 215 is still on the network and see if there are any issues adding that swtich. if I can do so, and there are no problems, is this an indication of a faulty switch? what further testing can I do, have I missed something in setup? If this brings the network down again, why cant i add two of these switches to each other/on the same network path (B and C were not even connected to each other yesterday evening when it went down again).

Cisco Switching/Routing :: WS-C3560-24PS - Rate Limit And QoS
Mar 4, 2012I am having an issue with VoiP phones giving me an insufficient bandwidth message. I have three remote locations connected to our main building using 2 Mb point to point ethernet solutions through TWC. Each remote location has a Cisco WS-C3560-24PS running IOS C3560-IPBASE-M, version 12.2(25) and have the cable modems plugged into port 1 on them. The remote buildings are labeled 192.168.101.xxx, 192.168.102.xxx, and 192.168.103.xxx. There are 14-16 VoiP phones in each remote building. The main building being in the subnet of 192.168.100.xxx. I have the 3560s connecting to a single port on a 2801 in the main building, all using the subnet of 192.168.253.xxx The phone server sits in our network at 192.168.100.203. I have created the ACLs, class maps, and policy maps on all of the equipment.
For the remote buildings I have the following:
ACL
===========
Extended IP access list VOIP
permit tcp any host 192.168.100.203 dscp ef
permit tcp any host 192.168.100.203 eq 5566
[Code]....
I have put a hub in to capture traffic via Wireshark to see if DSCP flags are being appropriately marked and I do see that all VoiP packets are getting marked with as EF. However, I have been receiving phone calls from people in the remote buildings stating that their phones will cut out, flash Insufficient Bandwidth on the LCD displays and then the call will cut back in. I am wondering if the 2801 is not applying QoS with the rate-limits in mind since it is set to 100 Mb, or is it an issue with trying to take 3 remote locations and bring them down into 1 port on the 2801?

Cisco Switching/Routing :: WS-C3560G-24PS Configuring Ip Dhcp Snooping Database With Scp
Feb 10, 2011Just spoke to the TAC and didn't get the information needed. When configuring ip dhcp snooping database I am adding this to my configuration:ip dhcp snooping database scp://dhcpsec@192.168.1.50/home/dhcpsec/switch1.dhcp.database.txt..I assumed that to do this I would either specify the password on the command line, similar to the way its done when using ftp/http, or that I would need to create a public/private key.I have enabled scp and can manually copy a file from the switch to the linux server. So I believe I have all the aaa commands correct. Cisco WS-C3560G-24PS System image file is "flash:/c3560-ipservicesk9-mz.122-55.SE.bin".

Apr 23, 2012I have a WS-C3560G-24PS service as a distribution switch with six (6) WS-C2950T-24 connected to it. In looking at the utilization on the inter connect links no one is running close to a gig speed and this includes the link between this switch and the core. The CPU load (6%) and memory utilization (30%) on the switch do not seem bad so what else does one watch to see if it needs an upgrade?
We are starting tohave discussions about any needed upgrades on the network. I have an ocassional user that complaines about low performance but looking through the network I can find nothing glaring on a consistent basis that says an upgrade is warranted. I am however looking at things such as the above. Utilization on links, CPU, memory, etc.
Cisco Switching/Routing :: WS-C3560G-24PS / Native Vlan Tagging And Vty Access To Autonomous APs?
Jan 14, 2013I've been experimenting with the 'vlan dot1q tag native' command on a switch and it seems as though tagging the native vlan breaks vty access to my access point.With the 'vlan dot1q tag native' commnand applied, I lose management connectivity to the AP with 'no vlan dot1q tag native' applied, connectivity is restored. Why is this? Is it safe to say that one can access the AP via vty lines using ONLY untagged packets?

Cisco Switching/Routing :: WS-C3560-24PS / WS-C3560-48PS - Port With WAP Goes To Err-disable?
Oct 11, 2012We have a Cisco switch in each office and every now and then the port that has the D-Link Wireless AP (DAP-1522) connected to it goes to err-disable state. Actually sometimes even a regular port that has a cisco phone connected may also go to err-disable state (less often). So I have to telnet into the switch and issue shut and no shut command on that interface to get it back to life, then it works for a few days or weeks until it happens again. Any suitable configuraiton for that interface, that would prevent that from happening or a workaround ?
Here's the info:

on my cisco switch (WS-C3560-24PS with 12.2(55)SE1), the port configuration is as below:
switchport trunk encapsulation dot1q
switchport trunk native vlan 45
switchport trunk allowed vlan 45,74
switchport mode trunk
no logging event link-status
no logging event power-inline-status
no snmp trap link-status

AP receives a DHCP IP in Vlan 45 and users connected in vlan 45 too. I would like to undestand why the AP is working properly because normally vlan 1 is not configured as allowed vlan on my switch and the native vlan is dedicated only to untagged ethernet packet.

Cisco Switching/Routing :: 2960G Configuring Ether-channel On Stack-wise Stack
Sep 24, 2012A site that i am responsible for has the following equipment installed:
2 x 3750G Switches configured as a stack using Stackwise - Collapsed Core/Distribution Layer
5 x 2960G Switches as Access Layer switches
WAN connections into the Core/Distribution Layer are all Gigabit Ethernet over Fibre.This is a dedicated CCTV Network with 50 Cameras all streaming video into the Core (decoders connected to access switches)Each 2960G has 2 links to the Core/Distribution 3750G Switches, 1 to each switch - Gigabit.I'm running rapid-pvst on all switches, so spanning tree is blocking one of the ports and effectively halving the 2 gig bandwidth. Next year our customer is going to add in a further 50 - 60 cameras.After monitoring the current loading on the ports in use, we have suggested to the customer that the 2 connections to each should be Ether-channeled together.

First interface takes commands no problem, keep getting the message that etherchannel cannot be configured across different switches in a stack when i try to put the second interface commands on.
