Cisco Infrastructure :: 2 6509-E Switches Connected Directly To Each Other While Using VRF-lite (Sup 2T)?

Apr 11, 2013

I am trying to test (if possible) the idea of having 2 6509-E switches connected directly to each other while using VRF-lite (Sup 2T). The idea is to have 3-4 separate networks. For example Net-A, Net-B,Net-C, Net-D. There is no PE router*, just these two switches. Also, there sin't any other access layer switches. All users connect directly to the 6509-E's via switch 48 port switch blades.  
Net-A and Net-B on separate VRF's, but able to talk to each other. Net-C and Net-D* on separate VRF's without being able to talk to any other. Net-D* will have a PE since it comes from an external network. This is something I would like to test in a lab environment, but I am not familiar with VRF's.

Cisco Switching/Routing :: 3750 Receiving CDP Packets From Switches Not Directly Connected

Jun 27, 2010

A specific switch port which happens to be part of a 2 switch 3750 Switch Stack is seeing multiple CDP packets from 3 extra switch port interfaces that are not directly connected. Noteworthy is that the far end devices have the correct CDP entries and I physically confirmed at least two of those connections that lead to the switch "upstream to the culprit switch". Tricky part is that its production so room for maneuvering is limited. At some point I disabled all Ports save for the real uplink and the problem momentarily disappeared. Re-enable the interfaces problem resurfaces. Is there an explanation, technique to eliminate the culprit with minimal disruption?

Cisco Switching/Routing :: Setting Up VRF-lite On Redundant 6509-E To Account For Chassis Failure?

May 15, 2013

setting up VRF-lite on redundant 6509-E chassis to account for chassis failure?   Let's say I have 2x 6509-Es configured with HSRP for 2 vlans, ServerA and ServerB.  So
interface Vlan10
description ServerA VLAN
ip address
ip flow ingress
standby 1 ip
standby 1 priority 105

I now need to create an environment where the Server VLANs can be provided for two customers and they need to be wholly separate.   On 6509-A, I make VRF CustomerA  and VRF CustomerB  and I assign Vlan10 to VRF CustomerA and Vlan20 to CustomerB.   Do I create the SAME VRFs on 6509-B with the same logic?

Cisco :: Difference Between Lite Entry And Base 2960 Switches

Jul 1, 2012

Thinking of getting one of those 8-port 2960 for a CCNP study. Is the difference between the C2960-8TC-S and the C2960-8TC-L models in Hardware, or in IOS? or both? And if it's in IOS, is the S upgradable to L?

Cisco Firewall :: NAT To IP Address Not Directly Connected To PIX 515

Mar 27, 2012

Can an ip address be NAT'ed to an ip address on a PIX 515 which isn't an ip address of a network directly connected to an interface on the PIX?
Specifically, can a host with an ip address of which is connected to a network whose PIX firewall interface is be NAT'ed to an ip address of which is not a ip address of an interface that is directly connected to that same PIX 515?
I've attached a PDF depicting the network topology and describing the above.My first response to this question is that it can't be configured to do this, but need either a confirmation or correction to this.

Cisco WAN :: 2800 Can't Ping Directly Connected Devices

Mar 28, 2013

I'm trying to configure a 2800 series router. .I'm consoled in and put a basic config on the router (see attached). After putting this basic config on, I plugged it into a small unmanaged switch, changed my laptop's IP and plugged it in the switch also. I can't ping the router from the laptop and vice versa. This is the second switch I've tried this with, so it must be.The first switch, I installed at location, connected a cisco cable to it and a local server, so i could remote in and finish configuration. In that scenario, I had plugged the switch into a managed switch and had the same result as I'm getting now--can't ping IP addresses (can't ping the switch's IP, not can it ping local IPs).

D-Link DIR-655 :: 10Mbps Up When Connected Directly Through Wired Connections

Nov 11, 2012

I've been trying to find a response or a fix to this issue for a few weeks now.My DIR-655 RevB router is currently at firmware 2.07NA, and has speeds of around 30Mbps down and 10Mbps up when connected directly through wired connections.However over wifi, I am only getting around about 5 Mbps down and 2 Mbps up.  I've tried the 'usual' fixes suggested on here, change broadcast signal to manual, not auto, shutting of QoS shaping, all of that. However nothing seems to be improving the speed.

Cisco Switching/Routing :: VPC Pair Of Nexus 7K And Servers Connected Directly

Jan 9, 2012

My Data Center has one single core switch where is connected several servers, one port is the link to the router wan and other port is the link to the FW, my boss wants to install 2 nexus in order to replace the single switch. All my network has only one address, for example if I connect two nexus 7010 in VPC and Domain, each nexus is going to has 2 modules with 48 port 10/100/1000 rj45 and i wan to connect servers directly to each nexus, with this figure i'm going to have a group of servers connected in two different nexus, Do they can have the same network considering that the nexus are in the same vdc and vlan and have only one gateway for both groups? If the answer is positive, which nexus would be the gate way for that address, the primary or secondary? Or i must have a different address for both group of servers, i mean for example and each nexus would be the gateway for that new address?
To have two nexus connected by VPC in a Domain mean that one computer connected to one nexus can share the same address or vlan with other computer connected to the other nexus????

Anything I need to do on Switch D so that Switch F can receive the VTP updates?

D-Link DIR-655 :: Router Is Not Recognizing Laptop As Directly Connected Device

Oct 27, 2011

I have a setup where there are two networks. A and a that are separated by the dlink router. I am able to ping from the 172 network to the 10 network using a laptop that is directly connected to the router and that laptop can also browse the web fine. However, I cannot ping to that router or access that subnet at all from the 10 network (if I try to access its LAN (the 172 network)). The 172 network is on its LAN and the 10 network is its WAN. I can access its WAN fine. Also, there the router is not recognizing the laptop as a "directly connected deivce" but its not preventing the laptop from using the router. I have tried to make the router as least secure as possible but still nothing.

I thought about making Static Route to point towards the router's LAN but the only option it gives me is the WAN for the exit interface.

D-Link DIR-655 :: Slowing Internet Down But Fine When Directly Connected To Modem

Jun 9, 2011

I have been using my DIR-655 for about 2 weeks now with Road Runner wideband services. Starting yesterday my internet became very slow and I discovered the cause was the router. I tried resetting it to factory settings and things will be fine and run smoothly for about 5-15 minutes but after that it goes back to being extremely slow. My speed tests would go from 10ms (normal) to 250-450ms. Before this issue occurred the Dlink was perfect, had full speeds. I am running a wire Ethernet connection.

I am currently using revB and tried upgrading firmware to 2.01NA which had no effect, but make my internet seemingly go back to normal for the first few minutes then nosedive again. I have also changed my speed/duplex settings in Network Config to 1gbs Full Duplex. I've also disabled QoS, and still no change. Not sure what else to do. When directly connected to the modem everything seems fine. The modem is also the provided Motorola SBG6580 which I have called Time Warner to set the modem into bridge mode and have the DIR-655 connected to it.

Cisco Switching/Routing :: 7206VXR - WCCP Redirection Of Non-directly Connected Subnets

Jul 18, 2012

I have a Cisco 7206VXR running 12.4(24)T3 IOS. It is configured with WCCPv2 using L2 mask redirection. I am using service groups and associated extended ACLs to select which subnets I want to redirect port 80 traffic from.
It is working fine for the subnet
int gi0/2
ip wccp 10 redirect in
ip address
... however, there is OSPF running between the router and a Mikrotik device directly connected to this interface. The gateway addresses for all the client subnets are on the Mikrotik. Traffic from other subnets, e.g., come in on this interface and I want to redirect those too. But it appears that the redirection doesn't work for those subnets (I don't see any hits on the relevant ACL for any subnet except
It seems like the router only wants to redirect traffic for subnets that it has an IP address in itself. Admittedly, all of the example configs i've found on are for redirecting traffic from directly connected subnets but I can't find anything that denies thie possibility of redirecting any traffic that comes in on a given interface.
The question is, is this how WCCPv2 redirection works? i.e., the router must have an IP address in the subnet to be redirected?

Cisco Switching/Routing :: Ping Break Between ASA 5550 / 2911 (directly Connected Via Ethernet)

UserNetwork - ASA5550 - WAN Router 2911 - ISP Netowrk - Branch Routers 877s / 1941s
Since last week we started noticing this problem that the branch users started to complain of slow application response.. After verifying it with the ISP and middle network we noticed that if i ping from my machine (ie usernetwork) to the WAN Router interface (facing the ASA) , i get time outs..  which is strange cause this is directly connected to it via ethernet cable.

Cisco Infrastructure :: Aggregate Policer Error In 6509

Mar 13, 2012

I am trying to find some background information regarding this error:
Cisco 6500 [SUP720-3B] %QM-4-AGG_POL_EXCEEDED QoS Hardware Resources Exceeded
Out of Aggregate policers.
What triggers this error? In this case, there are QoS policies configured at the interface level. The 'show platform hardware capacity' command shows that there are1024 policers supported. What counts as a policer? Is a policer each instance of a class using the police command? I see where there have been some suggestions to use VLAN based policies instead of interface policies and others suggesting to turn off 'qos marking statistics' but I would really like to understand the details of what causes policers to be used up and how to approach fixing this.
I am trying to understand how this works under the covers but can't seem to find any documentation anywhere defining the details.

and an 8 port fibre module (WS-X6408A-GBIC)

I'm looking to replace this with something with 72 ethernet ports and 8 fibre ports

Access Switches:
2x 3500Replacement needs at least 48 ports and 2 fibre modules each

and 2x 5500Replacement needs at least 72 ports and 2 fibre modules each.
