Hi , with interconnecting the Cat3750(C3750-ADVIPSERVICESK9-M,Version 12.2(25)SEE4 with a distribution Cat6509(with MSFC card) that gives us access to a gateway router.Between the two switches we only use switchport access mode with the same vlan-id ...

Hi , have you already gotten into the interoperability of Cisco 7921 phones with the 802.11i secured roaming techniques?When acting with 3rd party infrastructure the handover delay is quite important. Despite the fact that the Pairwise Master key of...

Hi, I was wandering if you already asked yourself about the nature of the wmm(802.11e) technique from the performance point of view and especially its relation to qos policing/shaping. The wmm normally is giving access with priority to voice /video...

hello ,i was looking quickly into spanning tree integration of the 440x with a wired switches but did not set a test yet. Maybe you already know if it's a vlan stp or port based spanning tree what they coded. Have you got any experience in the operat...

Hello , thanks for your input according this. That confirms what we've observed and but I thought were some firmware upgrades since.Thank you. Best regards , Michal

Hi , thank you for your feedback and it looks like in certain deployment ( for example if the client requires having voice and data allowed on the same ssid ) we should look into shaping to assure the coexistence of both services. BR , Michal

hello Eric ,thank you for your feedback according stp in 440x switches. Indeed the feature is not critical but i checked it again by mirroring the ports and it is not 'talking' with per vlan STP of 3560 or 3750. From the integration point of view yo...
