I'm having an issue with the voice quality because the switch ports are not honoring the DSCP values. I'm assuming DSCP values are rewritten as packets traverse the LAN. Is there a way of forcing the switch to honor the dscp value without turning on...
Hi all, I don't have the switches so I couldn't do the test myself.But as you know you can manipulate the root bridge priority by either put in:sw1(config-if)#spanning-tree vlan 1 priority <0-61440> (the lower the better)orsw1(config-if)#spanning-tre...

I can't seem to get any of my serial connections to ping. I have three routers. One of the routers has multiple serial interfaces that branch out to the others. I went through all steps in my CCNA workbook, following everything to a T, but still noth...
Resolved! StackWisePlus on 3750x
Greetings. I just set up a new 3750x stack of four switches and it's working fine. However, the StackWise is running at 32G, not 64G, which, according to the Data Sheet from Cisco, StackWisePlus is supposed to be 64G when in Full-Duplex mode. Of cour...

Resolved! CoS and Ethernet and Trunking Question
I've been doing some Cisco training and question came up "Is CoS supported in Ethernet?" I had presumed sobut the answer said that CoS was only supported on 802.1q and ISL trunks. So my question is - if you configure"auto qos" on an access switch p...
Resolved! 6500 server farm load balancing
Hi,I have a client who could benefit from hardware based server farm load balancing on a Cisco swtich. As I understand it, the 6500 platform is the only one having this feature. What hardware module is required and/or what software features?How well ...
Our network has two routers that contain two EtherSwitch modules. Thetwo routers are connected together by bridge groups. The EtherSwitch to Router is trunkedby dot1q trunking. All traffic internally can talk to each other correctly, but when dealin...

Hi All,I'm considering to get two 3750 switches stacked as our distribution switch. I'm still doing L3 to the core and L2 to the access switches. I don't have to put enhanced image on 3750 switch since we can use EIGRP stub on IP base image for the d...
Resolved! Switch can't ping outside local subnet
I recently installed a 3750 (24 port) into my network and trunked it (dot1q) to a stack of existing 3750s.The VTP settings seem correct: the new switch is getting the vlans across the trunk and the revision number looks good.Interface Vlan1 is assign...
Can anyone tell me what the benefit (if there is one) of configuring a L3 VLAN on a switch and assigning a switchport to the vlan for a single point to point connection with another switch? Would it not be a whole lot easier just to configure an IP a...
