LAN to MAN mainframe connection)? How would the clear ARP affect new communications attempting to be initiated between interfaces (ex. LAN to MAN mainframe connection) on the PIX?</P><P></P><P>After clearing ARP table on the PIX (for different issue) users on the LAN int indicated that they were intermittently receiving "timed out" messages when connecting to the mainframe on the MAN int. Other devices (internet router, IPS, etc were also booted at same time of PIX clear ARP command making it hard to figure out what may be causing communication issue).</P><P></P><P>When bringing up a IP device on the LAN that has a new MAC what devices would/should be refreshed to update ARP table entries? I am questioning if the PIX ARP table is the most appropriate or first place to address resolving issue when bringing up IP device with new MAC.</P><P></P><P></P> Fri, 21 Feb 2020 08:07:07 GMT https://community.cisco.com/t5/network-security/clearing-arp-table-on-pix/m-p/402308#M558762 tsussman 2020-02-21T08:07:07Z Re: Clearing ARP Table on PIX https://community.cisco.com/t5/network-security/clearing-arp-table-on-pix/m-p/402309#M558763 <HTML><HEAD></HEAD><BODY><P>Are you tried with PDM ?</P><P>please try with latest PDM Version</P><P></P><P>Thanks</P><P>Karthik</P><P></P></BODY></HTML> Mon, 02 May 2005 09:01:08 GMT https://community.cisco.com/t5/network-security/clearing-arp-table-on-pix/m-p/402309#M558763 mkkeyan 2005-05-02T09:01:08Z Re: Clearing ARP Table on PIX https://community.cisco.com/t5/network-security/clearing-arp-table-on-pix/m-p/402310#M558764 <HTML><HEAD></HEAD><BODY><P>I don't understand your suggestion.
