pinging broadcast address on router -vs- switch
Hello, Have a 3800 as a GW router & a 6500 L2/L3 switch with Vlans 12-18 for mgt traffic. Interesting I can use the broadcast ping command (ping 10.15.12.255) for vlan 12, but none of the others reply like vlan 12. Vlan 12 is the only vlan to go through .1-.254, but vlans 13-18 only receive a... -

Thanks all...I'll try a few of the recommendations and let you know. Will close out for now. -
router on a stick design flaw
I may try to move the sub-interfaces to the 6509 and use a /30 P2P. However... My only question is....since all subnets 10.15.12.x-10.15.20.x reside on a /24 mask, do I need to add a static route or helper address for the /24 subnets (600 hosts) to be routable out to the new /30? For example... -

router on a stick design flaw
Hello, I have a c3800 router as my GW to/from my corp network and test mgt network. On the 3800 router, I configured sub-interfaces for vlans 12-20 as router mgt in the test network. Interface g0/1 is connected to my 6509 in trunk mode for vlans 12-20. This has worked well for quite a few... -
OSPF between 6506 & ALU 7750

OSPF between 6506 & ALU 7750
Hi Cluebird, I did check MTU before and matched both 9198, and decided to recheck. On the Cisco g1/2 interface, I had matched to the ALU router interface "to-C6506", not the physical interface. Once I changed that to match the 6506 both 9212, OSPF now up! Does it matter whether the ports are... -

VoIP calls not seen unless I mirror them to a repeater hub?
Hello, I have a VoIP generator that has two seperate ports for the call to establish and connect. I currently have a ports 0-3 (from the voip-gen) on a Cisco6506 (vlans 400-403) and ports 4-7 (from the voip gen) connected to a Cisco 4948 (vlans 400-403). However, I cannot see them unless I... -
Cisco LAG to Alcatel-Lucent 7450
Running some pretty old stuff here on a Cisco 6506 (IOS c6sup2_rp Software (c6sup2_rp-PK2SV-M), Version 12.1(26)E), but trying to see if I can LAG a few GigE ports, and not having any luck. Is this supported or am I to use EtherChannel? On the ALU 7450, it's really simple on the 7450, but... -

External DHCP server with Linux or Win2008 work?
Quadratic... Considering my new router IP interface = 10.77.50.1, what happens to the existing default-router 10.115.60.1 IP in the DHCP Pool? My undertsnading was that you also needed a gi-address = the default-router 10.115.60.1? -
Cisco DHCP Pool conversion to Win2008 v4/v6 help?
I normally use Cisco DHCP Pools for DHCP Clients, but was told we're moving to extrnal DHCP servers yet TBD. Any TT members have working examples of Win2008? The only catch in my environment is i need to use Vlan ranges as i did with the DHCP Pools. I'd like to see if anyone has had success...- dvtestguy

Replacing Cisco DHCP to Linux
Hi, I'm replacing an older Cisco Router which was being used for DHCP Pools, NAT, ACL in favor of Ubuntu Linux Server. I've loaded the SW, started configuring, but had a few questions. 1) My Cisco DHCP Pools & Sub-Interfaces were setup due to Vlan traffic isolation per Client. On my Linux...- dvtestguy

Cisco/MS Mediaroom Server configs/topology
Any configure a Cisco environment using MS Mediaroom Personal Server for VoD/IGMP? If so, can anyone send me some good information how to configure my Cisco switches/router for the MSPS VoD content via IGMP? I also have two STB (Cisco SA & Motorola) as well. Thanks! -

Cisco STB port configurations...
VinceWhirlwind, I agree, some of the recommended configs didn't make sense. Yes, STB=Set-Top-Box & VoD=Video-on-Demand. I'm a pure data guy and never really hooked up STB/VoD, so I'm new at this area. The networking is fully routed, VTP Server/Clients are all set, etc. At a high level, this...
