I am not sure about your question. But Cisco has various products for out-of-band management. For instance the Cisco AS2509 and AS2511 Access Servers. They connect up to 16 routers with either an octal cable or roll-over cables. The octal cable has a scsci connector on the far end and breaks out into either 8 or 16 RJ-45 cables. These are connected to the console port of the router. However the Cisco AS2500 series are widely used, they're end-of-line for quite some time. Replacement product is NM-16A/S or NM-32A/S module for modular access routers such as 2600 and 2800 series routers. HTH --Leon * Please rate ALL posts. ... View more

Did you verify if CW is actually receiving SNMP replies from the missing devices? You can run snmpwalk from the command prompt on the CW server: %ProgramFolder%\CSCOpx\objects\jt\bin\snmpwalk -v 1 -c community 10.0.0.1 If the system is unresponsive, check if you have reachability from CW server using ping and traceroute. Review your configuration. Pay attention to the management VLAN, VLAN 1 by default. Does it have (correct) a default-gateway configured? For background information on Campus Manager ANI discovery I recommend that you read the following document: http://www.cisco.com/en/US/products/sw/cscowork/ps563/products_tech_note09186a0080094949.shtml#s1 HTH --Leon * Please rate ALL posts.

Switches like 4x00 and 6x00 come with a modular chassis that'll fit various modules. A supervisor engine is required for modules to work. In the late 5x000 series the supervisor engine could be complimented by a route-switch module (RSM) to perform layer 3/4 switching. The Catalyst 4x00 and 6x00 integrate these features in a daughter card called multilayer switch feature card (MSFC). The MSFC comes in various version such as 1, 2, 2a and 3. The MSFC is mostly coupled to the Supervisor engine model (I, II, IIa). Besides the MSFC the Supervisor houses another daughter card called the policy feature card (PFC). The PFC offers high performance security and qos features that are processed in hardware instead of using processor time.

You created a physical loop by cabling two ports of the switch to one hub. The hub receives the frames on port-A and forwards it to all other ports (including port-B) the switch receives the frame from port-B and inspects the source and destination address. Since it is a loopback frame which originated locally the switchs displays an error. A hub is considered an OSI layer-1 device. It copies and amplifies the recieved signal to all connected ports on the hub. Whereas the switch (aka. multiport bridge) is an OSI layer-2 device and forwards frames based on the destination address to the recepient or the nearest path to the recipient. Break the loop by removing cable from port-B. HTH --Leon * Please rate ALL posts. ... View more

You can either use bugtoolkit (requires CCO account) or read the releasenotes to find out about caveats in IOS releases. For instance if you have 12.4(6)T installed, you can read about caveats that where fixed in 12.4(9)T but affect the current release. It useally has a section with open and resolved caveats. If the particular technology affects your IOS you can decide to upgrade. If a bug has a big scope or if many bugs affect a certain release Cisco declares it as a "deferred" (DF) release.

The specifics of the keepalive packet are not disclosed on CCO. However, just as with CDP, VTP, and STP packets they are not forwarderd beyond the remote (switch)port.

Hello, There are multiple solutions to run RIP over a MPLS network. If the customer is using a IP VPN service, customer routing protocols can be deployed over the VRF's. Generic Route Encapsulation can be used to tunnel the RIP messages to the neighbor accross the MPLS cloud. If the next-hop routers is no more than 2 hops away, unicast routing can be used to statically define the RIP neighbor. HTH --Leon * Please rate ALL posts. ... View more

To migrate to EIGRP it's best to change the distance for RIP before configuring your routers. Give RIP preference over EIGRP for routing stability. This can be done without down time. router rip network 172.16.0.0 distance 89 The default administrative distance for RIP is 120, wheras EIGRP is more preferred due to it's AD of 90. Setting RIP to 89 will maintain RIP learned routes in RIB during installment of EIGRP protocol on your network. Now you can safely configure EIGRP. router eigrp 1 network 172.16.0.0 Review your network configuration. Are all neighbors visible and have all routes been exchanged. You should review the topology database on all routers for routing accuracy. When everything is to your satisfaction you schedule a maintenance window (i.e. downtime) to convert your network to EIGRP. You'll do this by removing the "distance 89" from the RIP process. Now your RIP routes will eventually age out and EIGRP will converge. You'll leave RIP configuration untill the topology has proven to be stable. If problems arise, you'll simple put back the "distance 89" under the RIP process to revert to the old situation. After some time you can remove the RIP process from all routers by issueing "no router rip". Hope this helps. --Leon * Please rate ALL posts. ... View more

Hello, Basically both commands do the same thing. Without a default-gateway your Vlan interface, by default Vlan1 can not communicate with devices outside of his local subnet. For instance if I have a NMS that resided on a subnet different than that from Vlan1 you need a router to forward packets to and from the NMS subnet. HTH --Leon * Please rate posts. ... View more

Hello, I assume your talking about static routes here. Say we want to forward traffic for 172.16.0.0/16 throug gateway 10.32.0.245.
