So after many, many (many, many..) years of watching the WLAN community hanging out at Cisco Live, random meetups, courses and the like, I have finally been able to participate in one and can now self-classify as one of the “cool” kids :D. My wife doesn’t agree. I’ve just spent a fantastic week with… Continue reading Ekahau ECSE Design
9800 Series These 9800 posts are part of a series including the following: Initial Setup Installing Cisco 9800-CL on ESXi Configuring 9800 WLCs in HA-SSO This post will cover installing the Cisco 9800-Cloud (Virtual) on ESXi running bare metal on an Intel NUC8I7BEH NUC. The Setup I’m using the following equipment/software for this demo: 1… Continue reading 9800 Series – Installing Cisco 9800-CL on ESXi
This nifty feature has actually been out for a couple of years but from my perspective companies have only been upgrading to 8.5.x in the past 6-12 months as older APs are phased out (1242/1142) and the code track is trusted as a stable TAC recommended one. Even with 802.1X being available on WiFi since… Continue reading Implementing Cisco iPSK with ISE
A fairly useless post for most but I like to have something I can reference later. This also definitely counts as a legitimate post so I’m back on the blog wagon! Scenario: I’m being lazy and want to copy a flash file over via xmodem because otherwise I’d have to turn all my switches on… Continue reading Set BAUD rate after boot and copy using xmodem
We’ve just had quite the head scratcher trying to install the ISE 2.3 OVA on ESXi 6.5 and figured we won’t be the only ones. Tl;dr – Convert the OVA to VMX then convert that VMX to OVF. Do not go directly from OVA to OVF. *Edit* 26/11/2018 – Can confirm this works for ISE… Continue reading Installing ISE 2.3 on ESXi 6.x
A quick post for those looking to deploy 1810W 1815W APs: PoE To enable the PoE-out port on Cisco 1810 / 1815 series APs (and I presume other models that support this setup). The document you are looking for is here: https://www.cisco.com/c/en/us/support/docs/wireless/aironet-1810w-series-access-points/200630-AP1810W-LAN-Port-Mapping.html Add the APs to an AP Group Enable PoE out via the… Continue reading Cisco 1810W 1815W APs – PoE, WLC Joining and Console Access
Either my google searches are terrible or there is a surprising dearth of articles when it comes to this topic. The scenario is you’re building a DHCP scope on a Cisco switch and need to convert your WLC IP from 192.168.23.52 into a hex value. This hex value is used in something called DHCP Option 43… Continue reading Converting IP to Hexadecimal for Option43
N.B. All configurations are based off the lab build seen in the introduction post. Power over Ethernet (PoE) is standardised into the the original 802.3af standard that provides up to 15.5W of power and the 802.3at standard which caters for up to 25.5W or 30W depending on which articles you read (confusing). These days many device types… Continue reading CCIEW – 2.4 Configure and Troubleshoot PoE for APs
N.B. All configurations are based off the lab build seen in the introduction post. I’ve completely skipped 2.2 Plan network infrastructure capacity and gone this which should also be a quick unless I’m underestimating things. 2.3 Configure and troubleshoot network connectivity for: 2.3.a WLAN clients 2.3.b WLCs 2.3.c Lightweight APs 2.3.d Autonomous APs Overview This section was… Continue reading CCIEW – 2.3 – Configure and Troubleshoot Network Connectivity
N.B. All configurations are based off the lab build seen in the introduction post. Hot Standby Router Protocol (HSRP) is one of three First Hop Redundancy Protocols covered in the CCNP R&S and, fortunately for our memories, is the only one required for the CCIE Wireless lab. In a nutshell this Cisco proprietary protocol allows two or… Continue reading CCIEW – 2.1.e HSRP
