- Run a Command to Flush the DNS Cache. You'll use a Terminal window to execute a command and flush the DNS cache on your Mac. Here's how you do that: Open Terminal by finding it with Spotlight, Launchpad, or Finder.
- Nov 18, 2019 Things can also go awry when you upgrade your Mac with new hardware, add memory, install a new graphics card, or change startup volumes. All of these activities can write new data to the parameter RAM. Writing data to the parameter RAM isn't an issue in itself, but it can be a source of problems when you change multiple items on your Mac.
- If you are using Mac OS X 10.7 (Lion), click the Downloads icon displayed on the browser. In Mozilla, choose Tools Downloads. To open the uninstaller, double-click it in the Downloads window. Note: If the Flash Player installer window does not appear, choose Go Desktop in the Finder. Scroll down to the Devices section and click Uninstall.
Shut down your Mac. Louie mac os. Turn your Mac on. Immediately press and hold the command + option + P + R keys. Continue to hold the command + option + P + R keys for a minimum of 20 seconds; longer is fine but not necessary.
Description
Enable media access control (MAC) flush processingfor the virtual private LAN service (VPLS) routing instance or forthe mesh group under a VPLS routing instance. MAC flush processingremoves MAC addresses from the MAC address database that have beenlearned dynamically. With the dynamically learned MAC addresses removed,MAC address convergence requires less time to complete.
For certain cases where MAC flush processing is not initiatedby default, you can also specify explicit-mac-flush-message-options that additionally configure the router to send explicit MACflush messages. To configure the router to send explicit MAC flushmessages under specific conditions, include explicit-mac-flush-message-options with the statement.
In the VPLS documentation, the word router in terms such as PE router is used to referto any device that provides routing functions.
In the VPLS documentation, the word router in terms such as PE router is used to referto any device that provides routing functions.
In certain cases, BGP updates sent by the provideredge (PE) device are delayed for 1 to 5 seconds.
Frog mall mac os. This happens when all of the following condtions aretrue:
BGP-based VPLS multihoming sites are configured.
The
mac-flushstatement is included in theconfiguration.a non-minimum designated-forwarder site (site-x, for example)transitions to non-designated-forwarder status
The BGP update being delayed corresponds to the explicit-MACflush notification message sent by site-x's PE device (PE2, for example).This BGP update message is not deferred if the designated-forwarderstatus is lost due to a locally-triggered event (for example, a localattachment-circuit interface going down). In other words, BGP updatemessages are deferred (in Device PE2) only when the designated-forwarderstate is lost due to external events taking place in remote PE devicesthat also hold site-x (for example, in PE1). Suppose, for example,that Device PE1 is the default designated-forwarder with site-x'slocal interface in the DOWN state. Device PE2 defers BGP update messageafter Device PE1's local interface comes back to the UP state.
