bug ,,? eh ? I dont think so .. Even on real routers when u have more than one NM-16ESW .. u might ( in fact u will ) face issues in pinging . This will b there if u have not STACKED the NMs together using clis and externa cable ,
On dynamips .. u cannot bring stacking up .. hence not pinging .. hence use only 1 NM-16ESW Thnx Gaurav Madan CCIE On Tue, May 25, 2010 at 10:36 PM, LJ <[email protected]> wrote: > If you use only 1 NM-16ESW then no problems.. else you have the problems you > described.. it is sorta kinda bug.. > > On Tue, 25 May 2010 13:15:41 -0400 > cciewannabe79 <[email protected]> wrote: > : Vlans created, SVI is up, still can't ping..I'm thinking I'll just use > : 3640's for my switches as everything works on those.. > : > : On Tue, May 25, 2010 at 1:51 AM, Bobola Oke <[email protected]> wrote: > : > : > ....just to add to what tyson scott said, do a show ip int brief on the > : > router you created the SVI on... is it up up... if it isnt, this means > you > : > have not created the vlans... > : > > : > best regards > : > > : > > : > On Tue, May 25, 2010 at 6:02 AM, Mustafa Yadav > <[email protected]>wrote: > : > > : >> Hi, > : >> > : >> I have come across the same sitiuastion many times.Before starting all > of > : >> routerts and swtiched start only r1 and sw1 .Try to ping .I think it > will > : >> run.It it runs it emans there is nothing wrong in your config. > : >> > : >> Try to create vlan in vtp transperent mode do not create unnecessary > : >> vlans.Use vtp pruning.Mostly between swtiches there are 3 links .I > prefer > : >> just run olny one of them as a trunk and define which vlans are allowed > to > : >> pass. > : >> > : >> Hope this helps. > : >> > : >> On Tue, May 25, 2010 at 5:52 AM, Tyson Scott > <[email protected]>wrote: > : >> > : >>> Have you created the vlan in the vlan database > : >>> > : >>> > : >>> > : >>> from global config mode > : >>> > : >>> > : >>> > : >>> vlan 12 > : >>> > : >>> exit > : >>> > : >>> > : >>> > : >>> > : >>> > : >>> Regards, > : >>> > : >>> > : >>> > : >>> Tyson Scott - CCIE #13513 R&S, Security, and SP > : >>> > : >>> Managing Partner / Sr. Instructor - IPexpert, Inc. > : >>> > : >>> Mailto: [email protected] > : >>> > : >>> Telephone: +1.810.326.1444, ext. 208 > : >>> > : >>> Live Assistance, Please visit: www.ipexpert.com/chat > : >>> > : >>> eFax: +1.810.454.0130 > : >>> > : >>> > : >>> > : >>> IPexpert is a premier provider of Self-Study Workbooks, Video on > Demand, > : >>> Audio Tools, Online Hardware Rental and Classroom Training for the > Cisco > : >>> CCIE (R&S, Voice, Security & Service Provider) certification(s) with > : >>> training locations throughout the United States, Europe, South Asia > and > : >>> Australia.
