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...

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...

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...

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...

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...

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...

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!

Q1) MOD 3 not showing IOS firmware....Is this normal? Q2) MOD 3 keeps shutting down its ports? I checked spanning tree and found the following: (which may lead to the ports being shutdown). cisco4503#show spanning-tree blockedports Name Blocked Interfaces List...

I have 6 of Linksys devices in a lab (SRW248G4, 48-port 10/100 + 4-Port Gigabit Switch) all supporting IP Management in one Vlan (10) for 200 devices that require IP's on subnet 10.10.10.x My question...All are daisy chained via one gigabit port, and noticed I'm seeing some collisions and slow...

I have a L2 IGMP environemnt that I need to change to L3 (unless my understanding is off?). I've configured the Source traffic (sending 100 Video streams starting Src 25.0.0.1 Dest 237.5.0.2) connected directly into the Querying switch (6506) in VLAN 193 (access mode). interface G3/7...

Anyone have exposure to both Cisco and Alcatel VPLS topology/features? Alcatel claims it can have 255 VPLS instances and 4k worth of VLANS (or they call, SAPs) per port. Whereas, Cisco needs an MPLS layer for VPLS to work? Is this true? Any info would be great with cisco's exposure to VPLS...

Have a VoIP gen tool able to generate 24k end-points (12k calls) to run into a Cisco lab network (See connection below), and the VoIP Gen tool claims that ports bandwidth is 100% for the Codec G.729 for each of the four ports connected. VoIP Caller (ports 0-3) <--> 6506 (ports f4/17-20) <--> Gb...
