When defining a QoS scheme for your network and carving up bandwidth on your router interfaces, do you need to create a classmap to specifically match IP routing protocol traffic, and then account for that traffic in your policy maps?   I recently saw this being done in someone elses network, but always thought that Network Control (CS6) traffic was automatically protected and given a certain level of "priority"...??? ...

Can anyone help me determine what files need to be deleted from flash to completely reset a Catalyst 9300-48U switch to factory defaults? I'm looking to remove everything that has been added since the time it was pulled out of the box... config, vlans, switch number in stack, authentication mode new-style, etc... I'm running version 16.6.2, so the "factory-reset all" command introduced in 16.8.x is not available on my switches. Thank you. ... View more

Can anyone speak about their experience with IP CCTV cameras, and how well they function across a wireless PTMP bridge network?    I have been asked about the feasibility of running several security cameras back to the main network via wireless bridges. Here's the proposed design: 3 separate parking lots, each with  3+ cameras, all wired back to a PoE switch for each lot. Each switch connected back to the main network via a wireless bridge, with all 3 bridges connecting to 1 Root Bridge.  Line of sight is fine from each lot, back to the main building. Attached is a basic drawing. I know that wireless cameras are an issue due to them being a constant transmitter and occupying the AP's entire duty cycle... Would it be any different for wired IP cameras, or would the bridges in this scenario be just as slammed? Thanks!   ... View more

Hello, I need help trying to figure out why phone registrations are randomly dropping and why we are seeing TCP-timeouts in the logs. All the phones operating at the same location as the CUCM are fine... all the phones operating at remote locations are experiencing sporadic and random tcp-timeouts. WAN connection between the sites is MPLS, and there is no firewall between the phones and the CUCM.  We are not seeing any issues with the network, and are not having any issues with any other applications on the network (including SCADA devices). TCP timeouts are sporadic and random, meaning all the phones at the same remote location do not experience the tcp-timeout at the same time, or even close to the same time.  For example, phone#1 may have a timeout at 8am, and phone#2 may have a timeout at 5pm.  And... the phones may go several days between tcp-timeouts, or they may have 2 in the same day. We cannot seem to find a rhyme or reason as to why & when, and we cannot replicate the issue on-demand. We also tried flooding phones with several concurrent calls and we were unable to duplicate the issue. phones are 8845's and 7841's running: Active Load ID:    sip8845_65.11-7-1-17 Inactive Load ID:  sip8845_65.11-5-1-18 and Active Load ID:    sip78xx.11-5-1-18 Inactive Load ID:  sip78xx.11-0-1-11 Cisco Unified CM Administration System version: 11.5.1.12900-21   Any ideas?   ...

Hello community members! Who out here has a good app for detecting SSID's and RSSI measurements in dB, when using iPad's or iPhones? I've been a longtime Android user and have always been a fan of the free "WiFi Analyzer" app, but I have not been able to find one that is comparable, to suggest for my Apple using colleagues. I see there are several paid-for and free "wifi apps" in the Apple store, but we're specifically looking for one that shows both SSID, as well as the Received Signal Strength level in a dB measurement. Attached are some screenshots from my Wifi Analyzer and what we're looking for... What do you guys use? Thanks, Brett ... View more
