I am pretty sure Tony that when I took the VSS class at Networkers last June in Las Vegas one of the benefits of the SXI4 code was that with dual sups ... you got ISSU. I am so sure of it because that is what we did in the class ( it was held the day before Networkers started ). From http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SX/configuration/guide/vss.html Quad-supervisor uplink forwarding provides these key features: •eFSU upgrades— You can upgrade or downgrade your VSS system using ISSU. See "Upgrading a VSS" section<http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SX/configuration/guide/vss.html#wp1169328> for more information about eFSU upgrades. scott > Message: 8 > Date: Fri, 17 Jun 2011 22:32:06 -0500 > From: Tony Varriale <[email protected]> > To: [email protected] > Subject: Re: [c-nsp] VSS - Horror stories, show-stoppers, other > personal experience? > Message-ID: <[email protected]> > Content-Type: text/plain; charset=ISO-8859-1; format=flowed > > On 6/17/2011 1:51 PM, Murphy, William wrote: > > We are running VSS for distribution layer switching in a campus > environment > > and have been quite pleased with it...
