Is the onboard interfaces on an ASR router (4x on ASAR1002, 6x on ASR1002-X) are fixed gigabit or are they 10/100/1000 ?
I assume the interfaces on the 8port Gigabit SPA module are fixed gigabit speed ports (why otherwise sell a 10/100 8port SPA module also ?) no ?
At home I have a Cisco 877 router, I also have Optus Cable internet and Telstra Business Direct DSL. I have configured the ATM interface for the Telstra DSL connection through the onboard DSL interface. I have also configured Fast Ethernet port 0 as a vlan2 port, which is configured for use with the Optus Cable internet (this is connected through an Optus Netgear CG3000 router). The Nethgear has DHCP enabled (192.168.0.xxx range), as does my Cisco 877 (10.0.0.xxx range).Firstly, the Telstra Business DSL is due to be connected tomorrow between 9am and 1pm, so it is not physically connected as yet.From my laptop connected to fa3 and using Console connection, I can ping all of the 192.168.0.xxx addresses that exist, as well as my own laptop and a VoIP phone I have connected to fa2 (laptop is 10.0.0.100, VoIP phone is 10.0.0.101 both DHCP assigned, not MAC Reserved either).I can use internet explorer on my laptop to connect to the Netgear router, but no other internet pages. I also cannot connect to my Fuji-Xerox printer at 192.168.0.20 through the web browser, yet I can ping it from the router.I don't have a huge experience with Cisco as yet, and everything I have learnt has been basically self tought. I am looking into doing my CCNA, once I achieve enough funds Now, what I am trying to achieve ideally is, to combine both the Cable and DSL services to in effect double my speed? if this isnt available, a load-balancing type of scenario would also be good. Both DSL plans have a 500gb download limit, but the reason I needed the Telstra DSL is the VoIP phones I am using won't connect through Optus (Optus have locked nearly everything out), and Optus will not give me a STATIC IP address with the Cable, whereas I have on on the Telstra DSL, I would like to Remote Desktop into my main PC eventually.
The IOS on my router is: C870 Software (C870-ADVIPSERVICESK9-M), Version 12.4(6)T7
The Optus Cable Modem IP is 192.168.0.1, the Cisco 877 router IP is 10.0.0.1
The current config (complete, with username & passwords ### out) is below: (Bear in mind there's probably many things thats not needed.Once I get the router working, I will configure my 2960 switch and have all devices connected through this. All devices on my network do not need to stay in the 192 range, they can be 10.0.0.xxx. The DHCP could be disabled on the Netgear (Cable Modem) if that's required as well.

How to hit the 32 interface nbar limit on an ASR? Our ASR1002 ESP5 is now grumbling: %NBAR-4-STILE_MAX_PD_INTF: NBAR protocol-discovery is enabled on maximum number of interfaces (32) supported by this platform..Is this expected to increase in future software revisions? (or is it a h/w limitation?)Is it the same limit regardless of ESP or will I get more (how many more?) if it is an e.g. ESP20?

I am little confused about the location of FIB table and adjacency table in both cisco 6500 series and fixed ports switches .In case of 6500 series switches
"Central CEF mode:The CEF FIB and adjacency tables reside on the route processor,and the route processor performs the express forwarding. Use this CEF mode when line cards are not available for CEF switching, or when features are not compatible with distributed CEF."
If line cards do no support CEF, then FIB and adjacency tables are built and are located on route processor( control plane ). Data plane operations are implemented in software and route processor performs those operations.
Some Cisco switches actually use different hardware to control the different planes. For example, the Cisco Catalyst 6500 is a modular switch that uses the Multilayer Switch.Feature Card (MSFC) for control-plane operations, and the supervisor Policy Feature Card (PFC) for the data-plane operations.
Supervisor module has has MSFC and PFC. MSFC implements control plane operation where as PFC implements data plane operation.But the first paragraph says in Central cef mode, both data plane and control plane operations are implemented by route processor. [code]
Do these switches implement the Central mode cef in same way as mentioned above. i.e
"Central CEF mode:The CEF FIB and adjacency tables reside on the route processor and the route processor performs the express forwarding. Use this CEF mode whenline cards are not available for CEF switching, or when features are not compatible with distributed CEF."Or fixed ports switches such as 3750 implement data plane operation in hardware where FIB tabe and adjacency table are maintained on Data plane.
see the attached diagram to explain the network. I'm trying to do a "port-to-port" layer 2 connection on an ASR that will bi-directionally bridge a physical interface to a sub-interface. I tried using " connect VLAN200 Gig0/1/0 Gig0/0/3.200 interworking ethernet " but I'm not getting traffic through the connection.
I don't think BDI will work because it requires a Layer 3 point. I have to make this Layer 2 switching.
Recently we have upgraded from a cisco 7200 environment to an ASR1002 having to migrate the configs as well.The command "ntp update-calendar" is not accepted in the config migration , any reason why ? doesnt the ASR have an internal hardware clock ?

Cisco docs indicate each module is supported in specific ASR and ONS but does not indicate interfacing between the two. If these two modules will communicate without error via multimode fiber?

View 1 Replies View RelatedI am trying to connect a 6509 switch to a 4503-E switch using single mode dark fiber over a distance of less than half a mile. Although a routine task, it does not work..We have a care 6509 switch where we concentrate all of our dark fiber connections for our remote sites. The 6509 switch already has 30 remote sites, most of them with 4503-E switches, connected in this way therefore it is a tested scenario. For the connections we use the GLC-LH-SM SFPs on both switches. Out of these 30 sites we had a similar problem with two of them, which we solved with the use of CWDM SFPs. With the CWDMs the fiber came up right away. However, I cannot keep using this solution because it is way too expensive! I had the losses of the fiber measured end-to-end and they are negligible (>0.5 dB).
In this latest case, like I said, we could not bring the connection up between the core 6509 switch and the 4503-E switch using the GLC-LH-SM SFPs. I then replaced the 4503-E switch with a 3560 and the link came up! Then I tried using a CWDM-SFP in the 4503-E, while keeping the GLC-LH-SM SFP in the 6509 and the link came alive again! Of course we already tried replacing the fiber patch cords with no luck. [code] I find it very weird for the link to work with the 3560 or with a CWDM in the 4503 but NOT with the SFP in the 4503!
I have a Nexus 5548UP that would be managed by two organizations. Is it possible to set IP addresses for mgmt0 and an SVI (or an L3 interface) without using the L3 daughter card? I don't want to route between VLANs, just to separate management traffic.

I have two switches (sanitized configs attached) and I am trying to bond int gi0/1 and gi0/2 between the two. Then I need int gi0/3 back to the main LAN switches. These are new Vlans created 982 and 983 for these switches. Question #1: do the configurations look correct? I haven't placed any laptops on the interfaces to test interconnectivity yet but I am wondering if it will work with no default routes.
The admin team needs these switches at location A for setup then they will be moved to Location B. The only thing that sucks for me is that the network admin before me created gateway interfaces for all the local Vlans on a main router as sub interfaces. For example, for these two subnets, I need to create subinterfaces below (at location A), which is why a gave the Vlan on the switches, ip addresses.
interface GigabitEthernet0/0.982
encapsulation dot1Q 982
ip address 10.98.2.1 255.255.255.0
ip flow ingress
no cdp enable
service-policy input mark-mplsqos-in
interface GigabitEthernet0/0.983
encapsulation dot1Q 983
ip address 10.98.3.1 255.255.255.0
ip flow ingress
no cdp enable
service-policy input mark-mplsqos-in
When I move the subnet to location B, I will also move the gateway. These two switches will be used mainly for a VMWare and HyperVisor environment so Vlan 982 is for VMA network and Vlan 983 is for management. The admin tells me the software needs to tag the packets, I am not sure if I care as the switches should handle that also.

View 5 Replies View RelatedI've just started a CCNA course and my lack of knowledge has me a bit stuck. My network is comprised of Cisco components and I'm semi familiar with them just from reading and looking through options. I currently am using a Cisco ASA 5520 on my network and I am trying to join another network via one of the interfaces. My network is 192.168.0.0 255.255.0.0 and my inside interface is 192.168.1.1 255.255.0.0. I enabled a second interface using a static ip of 10.0.0.1 with a subnet of 255.255.255.128. Connected to that interface, I have a Fortigate firewall at 10.0.0.2 255.255.255.128. I can ping just fine from the Fortigate network to the 10.0.0.1 interface on the Cisco ASA 5520 network, but I can not ping the 10.0.0.1 interface (or anything past it) on the ASA 5520 from any computer on the Cisco network. I've read that ACL's and NAT have to be done as well as enabling traffic between interfaces with the same security levels. (both interfaces have security levels of 100 and the option is checked to allow traffic).
Note: each network has it's own internet connection. The connection is to share information on servers on both networks with each other.
I am trying to add WCCP to be configured for websense. My first option seems to be either purchase an IPServices license for the stack of 3750E switches, but i am thinking this will require us to license all three switches in the stack. The second option i am looking at is to do the WCCP configuration on the 2800 router we have on the edge. The problem is both Gig ports are in use, one going to the firewall and the second going to the ISP. My first question would be, which option is better in terms of manging as well as cost of implementing it.The second question is, if WCCP on the router is a better option, what is the add on module i should be looking to get to add the additional ports to hook up the Websense cache.
