I want to know if is it possible to configure QoS on a 4500 Sup7 on a Layer 3 routed port like the following example (Similar to CBWFQ on IOS Router)?
View 3 RepliesI configured the interfaces individually at L3 and could ping across each link Example:
4500 Switch 2: 6500 Switch 1
int t5/1 - int g3/17 1 Gig fiber link
tore down config
tried second set of interface
int t6/1 - int g8/17 1 Gig fiber link
Ping successful

We recently had a contractor deploy a 4500 catalyst switch with a WS-x45-SUP7-E. After installation and configurations, HP openview is detecting a "downed" interface on the 4500 chassis that is not in the configuration. I have attached an image with the interface circled. We assumed that it may be a configuration issue with openview, however after running diagnostics with a network analyzer, the same ip address for the down interface is still detected. Is this some sort of internal virtual interface on the SUP7?

1. Switch 3750-X
2. VLAN 100 - ( SVI IP address 192.168.100.1 /24)
3. VLAN 200 - ( SVI IP address 192.168.200.1 /24)
4. routed port gi1/0/48 (IP address 192.168.150.1 /24). Note: this port is directly connected to a firewall ASA 5520 port IP 192.168.150.100 /24
Ip routing is enabled on the switch and inter vlan traffic is flowing ok. I can ping the routed port gi1/0/48 from any computer connected in the VLAN 100 or 200. For example computer with IP 192.168.100.25 can ping the routed port 192.168.150.1. Switch can ping firewall port 192.168.150.100 and the 'sh ip route' command shows the network 192.168.150.0 /24 as directly connected network.
any computer in the two VLANs CANNOT ping firewall ASA port 192.168.150.100 Is it because inter VLAN routing does not work with a routed port on L3 switch? I looked up fallback bridging, but it is meant for non IP traffic.The goal is I am trying to set the ASA port as an internet gateway for VLANs.
I have a switch layer 6500 series connected to a firewall, the port configuration between them is layer 2, in another words I do not configure an IP address in the Cisco switch port to conected it in the firewall, but when a apply a policy on firewall it lose communication with others vlans, just the vlan that is connected between the switch and firewall works, attachment the design. I think that is necessary to configure the connection between the firewall and switch as layer 3 ( a port with IP address in the switch), but I would like to know why? The switch is configured with about 10 vlan and it is a inter vlan routing, a default route is configured in the switch where the gateway is the firewall.
View 5 Replies View RelatedI've got a bunch of 3750-X switches all running IP Base and acting as a routed access layer. They run OSPF in a totally stubby area with the distribution layer (Nexus 7K) as the ABR. We also have a physically separate management network into which the fa0 management interface of the 3750-X is connected. The management network itself runs OSPF and has multiple subnets and external access.
On the 3750-X, I'd ideally like to be able to run some sort of separate OSPF process for the management network or at the very least have a static default route for management traffic pointing out the fa0 interface, but clearly not have it interfere with the main default route for data traffic coming from the N7K ABR. Normally I'd just create a management VRF, sling the fa0 interface into it and run a separate OSPF process in that VRF. The problem is you can't create VRFs in IP Base! Surely there must be a way to do this? Cisco don't really expect customers to upgrade to IP Services just to have a working OOB Management network, do they?!

We are about to install a new network consisting of Cat 4500s with Sup7E at the Access Layer, with Nexus 7000 at the Distribution and Core layers. We have 14 floors with at least three 4500s on each floor. Within the office block where the Access Layer and Distribution Layer reside we need to support secure borderless networking using 802.1x to place users from different parts of the business into segregated networks at layer 3.All switches will have the feature sets to support MPLS/ VRF / OSPF / EIGRP / BGP etc.We quickly dismissed the idea of using VRF-Lite due to the sheer number of Vlans we would need to managage and maintain, the point to point links alone just to get one additional VRF on each floor required far too many Vlans.As a result we are now considering deploying MPLS. The obvious benefits include scalability and manageability, the fact that all switch to switch links can now be routed, instead of having to using SVIs.

I have a collapsed core design with routed ports between all components. Access layer switches, data center switches, core/aggregation. All routed (no spanning-tree at all).Now...I have to add an IBM BladeCenter with a BNT layer 3 switch to my topology. However, those nasties don't seem to support routed ports.How can I have a routed port on my cisco switch and a standard access port on the BNT and still establish an adjacency with an SVI?

The port is generating lot of giants and after a while it also distrubs other routes ( Port1 to Port 16), configured with Vlan11 and port 22 as routed port.I have checked the routed port through wireshark the maximum frame size is 1514 and configured the MTU to 1514, giants are not showing any more but after 10 to 12 hours switch gets hang. Either to shut the port or to reload the switch to get switch and other layer routes to be normal.
I have checked speed and duplex settings same as E1 converter. Full duplex. 100 Speed. Why switch is not behaving normal. If I shutdown the routed port it is normal.

View 7 Replies View RelatedWe are currently designing Layer 3 to the edge EIGRP solution for our customers. The network is a hybrid of collapsed core (Core to access) as well as a three layer design (Core/Distro/Access) for connectivity to the Data Centre, Internet, Wireless Blocks etc.The core of the network contains two 6509-E switches interconnected on a Layer 3 Port channel (no VSS). Access Layer switches (3750-X series running Stackwiseplus protocol) connect to the core switches over p2p routed links and Distribution layer switches (3750X stackwiseplus) provide connectivity to the Data centre, Internet, wireless blocks etc.
The access and distribution switch stacks(Cisco 3750-X) are set up with two or three member switches with uplinks multihomed to the primary and secondary core switch with each uplink included in EIGRP. In each of the stacks, one of the switches controls the operation of the stack, which will be the stack master.As the Cisco Stackwise architecture is not SSO-capable but NSF aware, all Layer 3 fuctions must be re-established during a master switch outage. To minimize control plane impact and improve Layer3 convergence, uplinks should be diverse and originate from the member switches instead of the Master switches in the respective stack. This is as per Cisco recommended design solution.The above solution can be setup if there are more than two switches in the stack. i.e. uplinks are configured on the backup member switch modules.
1.But what about stack with two switches..Which switch should be set up as the Master for a two member stack with uplinks to the core primary and secondary from each switch(Master and Backup)
2. For Layer 3 routing, does the routing takes precedene over switch failures? Say for eg. In a two member stack, the master switch with uplink to primary fails, does EIGRP provide a fast convergence to route traffic via backup secondary and does not wait for the control plane on the switch stack to converge? All the access to core links will be set up for ECMP.
Configured Layer 3 portchannel from 6500VSS enabled switch to two different 6500 standalone switch. Configured first ip on VSS switch, second ip on standalone switch1 and third IP on standalone switch2. My question is
1. Will the portchannel be up?
2. If port channel is up, will I able to ping the connected IP's.

View 1 Replies View RelatedWe have recently purchased a Cisco 4506 that has several Gigabit Ethernet modules installed.One of the Ethernet Gigabit modules - a WS-X4424-GB-RJ45 - is being picky with who it talks to at Gigabit Ethernet.
If I plug a laptop into one of it's RJ45 ports using a Cat 6 cable, nothing happens. No link light, no notification of link up or down on port statistics, absolutely nothing.If I plug a server into the same port it works fine at Gigabit Ethernet (even using the same Cat 6 cable).I can get the module to recognize a laptop if I fix the speed/duplex on the laptop to 100Mb/Full. I have tried this with other staff laptops from different vendors (HP / Dell / etc.) all with the same result.
The module directly underneath this module - a WS-X4448-GB-RJ45 - works fine for both laptops and servers. We have tried swapping the module positions but to no avail.
