Cisco Switching/Routing :: Configure 7600 Ethertype
Mar 18, 2013
I have Cisco 7606 and wanted to test whether Cisco can drop frames due to invalid v lan ether type . i have configured the ports as
interface GigabitEthernet5/1
no ip address
switchport
switchport trunk encapsulation dot1q
switchport mode trunk
interface GigabitEthernet5/2
no ip address
switchport
switchport trunk encapsulation dot1q
switchport mode trunk
I have configured port also with encapsulation trunk dot1q ether type 88a8. i injected traffic with v lan ether type 0x8100. I expected to see drop traffic , however traffic passed in port to port.

ES20+ QoS. As I understand for these cards QoS is MQC; i.e. similar to that of normal WAN cards
1- If i have 7600 with ES+ card only then I dont need to configure global command "mls qos" and the concept of trust boundries "mls qos trust dscp" will not exist , correct ?
2- For below output, why "show mls qos queuing" is giving an O/P similar to that of WS-X6xxx LAN modules.Also why it is WRR when scheduling is not configured.I expected that command will not work with this module as it is similar to WAN modules.

When mutiple Policy based routing configured on 7600 routers, did the router performace degraded with the number of policy based routing rules?Also, did 7600 running 12.x use per-flow based routing or per packet based routing?

I am trying to bridge the traffic(including different vlan traffic) from rtrA to rtrB using "bridge-group" functionality.I achived the same using a 7200 using the below configuration. [code] When I tried the same using 7600 router ping failed between rtrA and rtrB. Then from the documents it seems "bridge irb" is not supported in 7600.Is there any other way we can achieve the same fuctionality ( eg: using switchport also fine) ?

I´m looking for an IOS on a 7609 SUP720/MSF3 that supports the NAT-PT feature (IPv4 to IPv6 translation). I searched on the Cisco Feature Navigator but the tool didn´t show up any IOS for the 760x platforms. I only got the feature "NAT-PT: Support for Overload (PAT)" with IOS 15.xS train.

I am a soon to be network admin and have never set up a network to an existing network. Steps you need to add a new location to a company's network. For example if they are using 8 Building with 7600 Routers and 6500 and you need another building and they are using MPLS or Private Network, or Internet.

I am a little stuck trying to troubleshoot unusually high cpu on 7600 Platform.This has been going on for many hours and not been causing a problem, but this doesn't seem replicated in our network and I am concerned about the cause.I have attached some output below, and disabled netflow on interfaces to free some switching CPU. How to track the cause of this? We only have routing protocols and 5 static routes to Null 0, so I cant see how this can be a route loop, but willing to stand corrected. Routes are learned from BGP with OSPF/MPLS internally on the network. This switch also connects to access switches on RIP and EIGRP.
No change has been made to this device when this problem started to occur so I am suspecting something about the traffic has changed or there is a rougue user? [code]

%%%%%%%%%%%%%%%%%%%%%%%%
duplex auto
speed auto
media-type rj45
negotiation auto
%%%%%%%%%%%%%%%%%%%%%%%%
note that the 4 lines above was not accpted in 7600. does these commands will affect the new config ?i just want to ask before im trying to apply this config to production network?

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.

I have run into a problem testing static route failovers using ECMP. I have an edge device (SUT) that has 2 NIC interfaces to an internal Loopback. Each NIC is a unique Gi port on an 7609 VLAN tagged with unique IP subnets. The 7600 is configured to route the loopback via the 2 NIC. I am using CEF in the network for other traffic performance testing. Using an external sniffer we can verify that when a ping is initiated externall to the SUT loopback a specific path is selected by the router.
Ping host ------Network-----7609 Gi1/21 (172.16.110.9)-----------SUT Nic1 (172.16.110.10)
| |
| -------Loopback 137.168.68.114/32
| |
7609 Gi2/21 (172.16.110.73)------------SUT Nic2 (172.16.110.74)
[code]....
Now, when the selected path is taken out of server (pulling cable for example), the 7609 is not clearing the routing table to indicate that particular path is down and failing over to the secondary path. Other things I have noticed is the show ip cef still shows both peers as well as the arp table but the interface shows down (show interface gi1/21 for example). I am running 15.1. My understanding is that since the ports are directly connected to the router, the ports should be detected as down and any association of the IP for the down port should removed. This should trigger the static route to update the static route for the end destination to use the second path and traffic should continue.

I have a port on 7600 connecting via Single Mode Fibre to my service provider. Service provider has 1000-Full with auto-negotiate. I am seeing following output on my 7600. [code] if this interface is only capable of doing 1000Mb, how come it is showing 100-Full. If I change to nonegotiate option (both my side and provider side), link goes down. My provider has confirmed they have 1000Full their side.

upgrading our small office network. We currently have about 75 employees with probably 125 devices on the network. I'd like to create about 10 vlans for the different departments and then configure intervlan routing as needed. Currently we have all unmanaged switches and it's just a huge broadcast storm on the network. We are upgrading our Cisco 800 router to an ASA5505 sec. Plus license. I need some recommendations on switches. Of course, this needs to be done as cheap as possible.... Is there a way to use the ASA to configure all the vlans and intervlan routing and access lists and use a cheaper switch to provide the access layer to hosts?

In our datacenter we have a 3750 stack with IP base image. I have enabled PBR and reloaded the switch. Show sdm prefer says i am using default template. The reason i want to use PBR is that we have 2 firewalls on the same work and want to be able to have granular control over which gateway out of the network they use but still be able to access all internal resouces accross wan and locally.
Created access list to identify traffic:
access-list 10 permit 10.2.3.59 (test workstation on vlan 3)
Created policy:
route-map TestASA permit 10
match ip address 10
set ip next-hop 10.2.0.3
Assigned policy to the user vlan3:
ip policy route-map TestASA
Results:It changed the default gateway to the above gateway but i could not access any resources on any other vlan, could not access resouces accross wan.

The layer 2 switches are connected to layer 3 Switch via trunks, and routing between layer 2 switch ports with configured SVI's on 3550. All working fine. Now I'm trying to configure routing between 2800 and 3550, I tried connecting both Straight Throught and Crossover cables to the 2800 Fa0/0 and Fa0/1 ports as well as the switchports on 3550
No switchport commands are configured however, the lights do not go on for both straight through or crossover cables. I tried connecting 1750 routers but same result. My goal is to have all the VLANS routed to the internet with configuring NAT translation the router.

If I have an ASA 5520 with an INSIDE interface, a DMZ interface and a WAN interface what would be the best way to configure NAT? If I configure nat-control and a nat (inside) 1 0.0.0.0 0.0.0.0 this will configure everything to be NAT'd when passing from the INSIDE interface out.My question is what about the devices I want to access in the DMZ from the inside for management etc? I'm guessing the ASA isn't smart enough to realise you're accessing hosts in it's DMZ interface so do you have to configure a nat 0 rule for every subnet within the DMZ you want to access or is there an easier way to do it? It's worth noting that the same devices will be accessing the OUTSIDE network and the DMZ network from the INSIDE network.

I have a customer who is on thr 192.168.254.x subnet and is using a Cisco 881 as their gateway.
They wish to create a second VLAN for the 192.168.253.x subnet.
The Cisco has Dialer0 configured for an ADSL connection.
I have partly configured the router but need some info regarding router a device on the 192.168.253.x subnet to the internet.
configure routing to the internet on the new VLAN and assist in setting up a DHCP server on that vlan. I have attached a copy of the current config.
