Does IPv6 support mDNS?

An mDNS message is a multicast UDP packet sent using the following addressing: IPv4 address 224.0. 0.251 or IPv6 address ff02::fb. UDP port 5353.

Does CAPWAP support IPv6?

CAPWAP can operate either over IPv4 or IPv6, as shown in the figure, but uses IPv4 by default. IPv4 and IPv6 can use UDP ports 5246 and 5247. However, CAPWAP tunnels use different IP protocols in the frame header.

What is mDNS in WLC?

With WLC 7.4 code Cisco supports Apple Bonjour Gateway functionality ( know as multicast DNS or mDNS) on the WLC itself. This helps you to deploy AppleTV, Apple Printers on different subnets to where wireless client sits.

What is split tunneling WLC?

Split Tunneling introduced to Flexconnect APs in WLC7. 3. x releases. This will allow certain traffic to be locally switched & all other traffic to Centrally switch from a Flexconnect AP. In this post we will see how this feature can be enabled & use it in Office Extend- Home user scenario.

What is the difference between DNS and mDNS?

Unlike the conventional DNS, the operation of mDNS is up to the level of local network since the operation of DNS takes place at global level. In the Zeroconf network, it works in the combination of the protocol DNS-SD. There is no need of manual operation in the network of zero configurations.

What is mDNS vs DNS?

mDNS | Multicast DNS. Like DNS, mDNS also resolves domain names to IP addresses. mDNS operate at local network level unlike conventional DNS which operates at global level. It works in conjunction with DNS-SD (service discovery) protocol in zeroconf network.

What UDP port and IP protocol are used by CAPWAP for IPv6?

CAPWAP uses UDP ports 5246 (control channel) and 5247 (data channel).

What is multicast VLAN feature?

Multicast VLAN feature When Switch A (Layer 3 device) receives multicast data for that group, it sends three copies of the multicast data to Switch B (Layer 2 device). This occupies a large amount of bandwidth and increases the burden on the Layer 3 device.

What is an OEAP?

Cisco’s OfficeExtend Access Point (OEAP) allows a Network Administrator to extend the secure, scalable, and manageable corporate WLAN across the internet to the Teleworker’s (employee’s) home.

Why do we need mDNS?

Multicast DNS (mDNS) provides a naming service system that is easy to set up and maintain, for computers on a local link. All participating network devices on the same local link perform standard DNS functions, using multicast DNS rather than unicast, and do not need a unicast DNS server.

Is mDNS a security risk?

If your mDNS service is exposed to the Internet, querying the service would allows hackers to collect information about your server (such as the MAC address information of the device, or services running on the machine) that could be used to prepare an attack.
