If I look at Firewall logs I see the tftp connection being allowed and then a blocked connection to destination port 29002 on the tftp server (my WCS). Any ideas what this is and what the WLC is attempting to do?</P> Sun, 04 Jul 2021 03:51:59 GMT https://community.cisco.com/t5/wireless/can-t-download-code-to-anchor-wlc/m-p/1799107#M8262 pinglis 2021-07-04T03:51:59Z Can't download code to Anchor WLC https://community.cisco.com/t5/wireless/can-t-download-code-to-anchor-wlc/m-p/1799108#M8263 <HTML><HEAD></HEAD><BODY><P>Are you using your WCS to push the upgrade ? If so, try doing this from a local TFTP server. 29002 doesnt ring a bell ... </P></BODY></HTML> Thu, 06 Oct 2011 20:14:14 GMT https://community.cisco.com/t5/wireless/can-t-download-code-to-anchor-wlc/m-p/1799108#M8263 George Stefanick 2011-10-06T20:14:14Z Can't download code to Anchor WLC https://community.cisco.com/t5/wireless/can-t-download-code-to-anchor-wlc/m-p/1799109#M8264 <HTML><HEAD></HEAD><BODY><P>Can you try upgrading using the Service Port?</P></BODY></HTML> Thu, 06 Oct 2011 21:38:28 GMT https://community.cisco.com/t5/wireless/can-t-download-code-to-anchor-wlc/m-p/1799109#M8264 Leo Laohoo 2011-10-06T21:38:28Z Can't download code to Anchor WLC https://community.cisco.com/t5/wireless/can-t-download-code-to-anchor-wlc/m-p/1799110#M8265 <HTML><HEAD></HEAD><BODY><P>OK, to answer my own questions this is how tftp works.
