24 Installation Guide for JunosV Wireless LAN Controller 6. Click the Security tab to view additional options. 7. Be sure to select Accept for Promiscuous Mode; otherwise, the communication on the virtual ports does not work. JunosV WLC uses the MAC address assigned by VMware if this option is not set to Accept; otherwise it, uses the system MAC address. Promiscuous mode is a security policy that can be defined at the vswitch or Port Group level in vsphere ESXi. A VM, Service Console, or VMkernal network interface in a port group allows the use of promiscuous mode to monitor all network traffic through the vswitch. By default, the virtual network adapter of a guest OS receives frames that are meant for it only. Placing the guest network adapter in promiscuous mode allows all frames passed on the virtual switch to be received if the VLAN policy for the associated group permits it. This can be useful for monitoring intrusion detection or a sniffer, if one is used to analyze all traffic on the network segment. 20

28 Installation Guide for JunosV Wireless LAN Controller Upgrading Mobility System Software on a JunosV Wireless LAN Controller You can upgrade JunosV Wireless LAN Controller (JunosV WLC) within the same release and from JunosV WLC to the next release. This topic describes: Upgrading Within the Same Release on page 24 Upgrading from Mobility System Software to the Next Release on page 24 Upgrading Within the Same Release To upgrade from JunosV WLC to a 9.0 Release: 1. Unpack the release_img.tar.gz file to a location from where it can be copied to JunosV WLC by using tftp or scp copy protocols. 2. Copy the.ina file (/release_img/public/wlcv0xx.ina) to the boot partition on JunosV WLC by using Trivial File Transfer Protocol (TFTP) or Secure Copy Protocol (SCP) copy protocols. For example, copy scp://<ip>///<path to.ina file>/<.ina file> boot<x>: 3. Then, follow the same procedure used for upgrading a physical wireless LAN controller. NOTE: Using SCP is faster than using TFTP; but SCP can be used only if the station where the.ina file is located a Linux station. Also, copying the.ina file from a location closer to the blade that hosts JunosV WLC results in faster file transfer rates. Upgrading from Mobility System Software to the Next Release To upgrade from MSS to the next release: 1. Create a new virtual machine (VM) for JunosV WLC by using the new OVA file for the next major release and copy the earlier configuration to the new VM. NOTE: Power down the earlier VM before copying the earlier configuration to avoid network issues. 2. Delete the earlier VM after testing to ensure that the new JunosV WLC has been created successfully. 24
