@Atags - so how did things work out on Mirror port for all those switchports, did it affect switch CPU performance. Also is it possible to send stack 1 mirror ports source to another stack member?   Anyone if you have experience or knowledge this would be very helpful. I have an 8 stack of Meraki MS225s and I am trying to mirror 48 ports from 1 switch and send them to a designated port on switch stack 2. Therefore, I will have 90 ports mirrored to one port on Stack 1....does that sound doable.  ... View more

Hi Jim - Im interested in whether you implemented the stretched HA pair? We busy planning on the doing the same with our MX250's in addition to stretched L3 stack using 4x MS425. Any insights or lessons learnt would be appreciated. ... View more

Hi, Ok please see my tests below; Remember they are not piggy backing any PCs off phones. The Phone ports are set up as access and not trunk   Before port settings   Before a packet capture from a live phone call ...  Network policy Subtype (2)      Application type [voice] (0x01), Flags [none]      Vlan id 4095, L2 priority 5, DSCP value 46 ...   After port settings (999 is just a dummy vlan)   After change now a packet capture from a live phone call Network policy Subtype (2)      Application type [voice] (0x01), Flags [Tagged]      Vlan id 118, L2 priority 0, DSCP value 46     Any thoughts on this now and why it changed it looked like? Also why did the L2 priority change also? Does this still look right for QoS?     Thanks ... View more

Hi. I figured out the problem incase this happen again to someone else or another case. The problem was not on the Meraki's. The issue was actually on the Cisco 9500 Core Switch. Someone must have turned off the DHCP service for some reason. After enabling back on, DHCP across VLANs now work. So this look to be resolved as of now. Thank you all again for your time with this! ... View more
