Cisco 8.0MR4 and mDNS

[Revital Gorsht]

Has anyone running 8.0.140.0 with mDNS enabled come across any issues?  We upgraded over the summer from 8.0.120 to 135 to resolve one issue and are now facing another in 8.0MR3, both related to mDNS... just wondering if we'll come across any other(s)?  R GorshtNetwork Designer | UIT - Network Development010 Steacie Science and Engineering Library | York University | Toronto ON Canada M3J 1P3T 416.736.2100 x22648 | F 416.736.5830 | www.yorku.ca

Re: [WIRELESS-LAN] Cisco 7.3 Code and ISC DHCP

[Revital Gorsht]

This is long overdue, but to close this thread: As of 7.3, global IP Routing is enabled and, by design, an AP will drop packets that are layer 2 broadcast and layer 3 unicast, as was the case with our DHCP offers since we had a broadcast address specified on the SVI. Once the "ip broadcast-address" statement was removed from the SVI, the AP was able to process the packet and receive an IP.  Hope this helps anyone else experiencing this issue...Thanks.-The EDUCAUSE Wireless Issues Constituent Group Listserv WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU wrote: -To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDUFrom: Jason Murray <jemur...@zweck.net>Sent by: The EDUCAUSE Wireless Issues Constituent Group Listserv <wireless-lan@listserv.educause.edu>Date: 10/19/2012 10:16AMSubject: Re: [WIRELESS-LAN] Cisco 7.3 Code and ISC DHCPOn 10/17/12 6:39 AM, Julian Y Koh wrote: On Oct 16, 2012, at 19:49 , Jason Murray jemur...@zweck.net wrote This is not completely related, but we just upgraded one of our Cisco routers, after the upgrade dhcp stopped working because one dhcp option was blank.

Can you share router model and software versions?The last time we had this problem, I documented it here:http://blog.zweck.net/2012/10/cisco-fails-to-relay-dhcp-requests.htmlWe have also seen this exact same problem on the Cisco 6509, although Idon't remember the exact software versions.-- Jason E.

Cisco 7.3 Code and ISC DHCP

[Revital Gorsht]

Our most recent shipment of Cisco 3600 APs came with a preloaded 7.3 image and appear to be ignoring the DHCP offers being sent to them from our ISC DHCP server. While spanning the port the AP is on, it is evident the offers are being sent from the DHCP server, yet the AP's debug messages insist its discovers are going unanswered. Once the AP is configured with a static IP, it will then connect to the controller, running 7.2, and downgrade its image, at which point we clear the config (so the static IP is forgotten and the AP is forced to use DHCP) and the AP accepts the same DHCP offer without fail. Wondering if anyone else who has migrated to 7.3 code with CAP3602I's and using ISC DHCP is experiencing this, or if this is specific to our DHCP settings? At the moment, I've got a case open with Cisco and am waiting on development to respond...Thanks.**
