We are looking for a solution that to use Sub-interface on a routed port on 6509, instead of using a SVI on it.Are there any different when using Sub-interface?
View 3 RepliesQuick question here. Using 3750E series switches with multiple VLANS configured. These switches serve as our 'core'. I have SVIs configured for the different VLANs and add inbound ACLs in each of the SVIs to control traffic between VLANS. This switch also terminates a P2P Ethernet link which connects to our Colo facility. The port used for this is configured as an L3 port. I noticed today that I was able to send traffic across this L3 link that I thought should have been blocked by an ACL I had in place but it wasn't. So the traffic flowed from a port in say VLAN 20 across this L3 link (assigned with an IP address). Would this traffic flow not cause traffic to be checked against an ACL applied in the inbound direction on the SVI of VLAN 20 (int vlan 20)? Traffic does get checked when routing between SVIs. Why would it not get checked when routing between SVI and L3 interface?
View 2 Replies View RelatedWe have a 6509 that was connected to 2 other locations(location A and B) and our local lan (location MAIN). We wanted to move the location A and B to a 3750 switch and only allow the traffic that needed to access our location MAIN to come through the firewall. The only problem I ran into is that before location A and B were on different interfaces so in the 6509 firewall the routes for traffic to our MAIN location was done by static routes.
I.E.
static (MAIN_intf,A_intf) 192.1.1.72 10.94.10.72 netmask 255.255.255.255 0 0
static (MAIN_intf,B_intf) 192.2.2.72 10.94.10.72 netmask 255.255.255.255 0 0
[Code]....
because it has a static overlap, which makes sense to me, but my question is how do I configure the network to get this to work? Do I have to reconfigure my network and access-list? Do I need to add more ports between the 6509 and 3750? I'm not sure if this is the best way to do what we want. If something is not clear I'll try my best to explain the setup, but I just took over for our I.T. guy when he left.
I put 10.10.10.72 instead I should have put 10.94.10.72. the routed port is on a different subnet than the computer I'm trying to access.
On a router I can use IP Accounting or Netflow to see what kind of traffic is moving over an interface. Are there any tools on a 3750 switch with a routed interface which would tell you who is hogging the bandwidth on that interface?

Actually i have 7600 router and all trafic passes through Gi0/1(Routed port) interface to 6500 series switch. I need to create a vlan on this router eg. vlan 10 Any how it is possible assign a vlan to routed port and traffic of wan interfaces and the vlan traffic passed together.
View 2 Replies View RelatedI have made a routed port on 3560G Switch and defined a pool 172.28.4.62 255.255.255.192 and connected to E1 converter RAD (4E1 to 4 FE) the E1 media is through Microwave on the other end same E1 converter is connected through layer 2 switch and defined a pool as of routed port configured in 3560G switch.
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.

How to configure traffic flow between computers inside VLANs and a routed port? Here is the setup details:
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 am getting alarms on Solarwind indicating interface down on "GigabitEthernet 4/7 - Gi4/d1" and "GigabitEthernet 4/8 - Gi4/d2" from our core switch 6509.Remote login to the switch does not show the interfaces when I do the "sh run" command. Now I am at site trying to identify and diagnose this fault.Looking at the numbering on the switch, it indicates to me the card where these alarms come from is from the 'intrusion dectection module'
how I may login and identify this interfaces and rectify these alarms.
How (and is) it possible to rate limit pps on an interface (physical/logical), on a 6509-E?The porpuse is to protect from attacks which lead to very high pps, bypassing traffic rate-limits, and effecting the device's performance

I am very new to configuring ports on a switch. My boss usually does the port configurations but I am starting to learn some of the basic commands. The commands I know how to do are; close a port by typing config t, int gi0/port# and typing shut. I know how to enable a port, but how can I add info to a port or copy settings from one port to another?
We have some ports that are configured for 192.168 addresses but most are 10.128 addresses. I need to configure a certain port to be able to receive 192.168 addresses.
I have 2 Cisco 6509 switches linked together via single Fibre as a trunk.I want to change this to a port channel where I will add another 3 fibre ports to the port channel but what order do I do this to minimise any disruption.
1-Configure PortChannel and add the 3 new ports, this will bring up the Port Channel but what effect will this have on traffic currently going over the single Trunk link? Will spanning tree go mad, how will switches react?
2-Convert existing Trunk link to Portchannel then add in new ports to PortChannel, I guess in doing this there will be a small hit on traffic as it changes to a port channel.
Created two 6509s as VSS with just one 10gb connection?I know it is recommended to use both the 10gb connections on the sup-720 from below configuration guide

We have a pair Cisco 6509 switch in which 2 * 48 Port 1G line cards and 1 * 16 Port 10G line Card, FWSM and Sup 720 are installed.We have Cisco UCS and HP Blade servers.Cisco UCS servers are connected to Cisco 6509 switch using Fabric Interconnect, and HP Servers are directly connected to core switches.Recently the team made many changes in the network. Upgraded the IOS in Cisco 6509 switch, Configured Port profiling , MAC Pinning , HBA Cards to UCS / Nexus 1000V Infrastructure. After this change they lost the connectivity to UCS and HP Serers. Every tower is checking at their end.

I'm working at a company that has several 6509 switches running CatOS. They have two of the 6509's running in vtp server mode and the rest as clients. I set up a new vlan from one of the vtp servers and it propagated out. The problem comes when I try to assign a port on one of the vtp clients to this new vlan. It gives me an error that the switch must be in vtp server mode to add/delete vlans. I'm not trying to add/or delete a vlan just trying to add a port into an existing vlan. I'm hesitant to put the switch in vtp server mode. Is this a CatOS thing or is there a specific command to accomplish this?
View 5 Replies View RelatedI have several closets with Cisco 3560 on the edge that I'd like to change the vlan that's used for the management vlan on each. In the core I have a Cisco 6509 with Sup720's.
I'd like to do this by changing the native vlan on the trunk port on the core 6509 interface that connects to the 3560. and leave the management vlan on the 3560 as vlan 1.
Seems trivial but what I tried didn't work and I didn't have the window to troubleshoot. I'll paste the simplified configs for the interfaces below

We 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.
We have two 6509 switches with one WS-X6704-10GE module in each of them. There is an optical cable between the two switches plugged in WS-X6704-10GE module on both sides. When you shut down the port on one side the other port still stays as up and you need phisycally to unplug the cable to have it down. The same behaviour is seen no matter on which of the two switches you shut down the port, the opposite one always stays as up and only removal of the cable makes it go down.
The ports are configured quite simply:
interface TenGigabitEthernet1/1
switchport
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1-10
no ip address
udld port
The IOS version is 12.2(18)SXF8

View 15 Replies View RelatedCurrent topology in network is such: web servers with content needing to be load balanced are in vlan 35 and these servers are directly connected to Core switch (two 6509 VSS) via 20 Gb EtherChannel.

View 3 Replies View RelatedHere's my problem. I'm going to be using Cisco 1941 routers at a bunch of remote sites. All of these sites have 2 comm paths out. Some of them have 2 IP/VHF radios and some have 1 IP/VHF radio and a copper link using Patton ethernet extenders. From the VHF radios the data hit our MPLS network back to our HQ and the sites with copper go directly back to our HQ. Everything ends up at a Cisco 4948 switch. The problem I'm having is that I want the routers at the remote site to use one ethernet port (G0/0) as the primary and the other (G0/1) as the backup interface. I've tried the backup interface command but the problem is that depending on where an outage occurs the ethernet link to either the radio or Patton stays up so it never switches over. We're using OSPF as our routing protocol and I'm sure there's something that can be done with it but I'm not sure what.

Should I keep the configuration on the physical ports and not configure the Port-Channel Interfaces? Do I need to configure port-channel load balancing? Is the channel-group mode sufficient? Goal is to basically create 2 links to the 2960 to double the bandwidth and provide redundancy.
