Well, interesting.. sometimes Cisco guys forget to import some cool features; I don't know why but it has been seen on some occasion. Better you down grade to the release which support baby giants....
For those switches that support up to 1530 bytes, the default MTU value is 1500. If you want to change this, use the global configuration command that is available for versions of software above 12.1(6)EA2. Here is sample configuration and verification: This URL might help... http://www.cisco.com/en/US/products/hw/switches/ps700/products_configuration _example09186a008010edab.shtml Regards, Masood Ahmad Shah -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Friday, January 04, 2008 3:06 AM To: Masood Ahmad Shah Cc: [email protected] Subject: RE: [c-nsp] MTU Issue on QinQ Eth link with MPLS Quoting Masood Ahmad Shah <[EMAIL PROTECTED]>: > Well, better you check current MTU settings using command > > # sh interfaces | inc MTU > > And cheers :) > > Yes of course you need to adjust routers MTU as well; if you are running > with MPLS or gre > Thanks Masood. I've run into a strange problem on the 2950's - Both devices are C2950G-24-EI (Which support baby giants), but the one with the more recent IOS is only reporting that it supports 1500 byte mtu?: Model number: WS-C2950G-24-EI System serial number: FOC0833X3M8 System image file is "flash:c2950-i6q4l2-mz.121-22.EA7.bin" No baby giant support: gc-sw-08(config)#system mtu ? <1500-1500> MTU size in bytes Whereas: Model number: WS-C2950G-24-EI System serial number: FOC1012Z5BJ System image file is "flash:/c2950-i6q4l2-mz.121-22.EA6.bin" Baby giant support: ESW01-BNE(config)#system mtu ? <1500-1530> MTU size in bytes I compared both images on the Feature Navigator, and there is no mention of any Features unique to the images other than "IEEE 802.1x - Auth Fail VLAN" on the EA7 vers.? ------------------------------------------------------------------------- This e-mail was sent via Data FX Online WebMail http://www.datafx.com.au/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
