Cisco Switching/Routing :: No IP Forward-protocol UDP In 2960?
Jul 10, 2012I am trying to enter this command in Cisco 2960 but the device is not accepting it. Is this because of IOS or this command is not available for 2960?

Cisco Switching/Routing :: 2960 Setup - Compatible Spanning Tree Protocol
Jan 9, 2012At a college I'm trying to setup a Cisco 2960 to be used on a VLAN 248 tagged on the uplink port that uses Spanning Tree/. Here is the following from the Cisco:
show interfaces trunk
Port Mode Encapsulation Status Native v lan
Gi0/1 on 802.1q trunking 1
Port V lans allowed on trunk
Gi0/1 248
[code]...
On the Alcatel OS6850-48L the following is setup: bridge 1x1 248 priority 3287 Vlan 248 802.1q 5/8 "cisco"
I cannot make a change on the Alcatel, I can only administer the Cisco. I was able to get things working fine (as a test) using a Net gear or HP switch instead of the Cisco. However we have a Cisco switches and would not like to have to buy HPs. Is there a compatible spanning tree protocol to use on the Cisco with the way things are configured on the Alcatel. I need to stick to standard RSTP (802.1w) ieee standards and not something Cisco proprietary.

Apr 18, 2012I have a collapsed core design with routed ports between all components. Access layer switches, data center switches, core/aggregation. All routed (no spanning-tree at all).Now...I have to add an IBM BladeCenter with a BNT layer 3 switch to my topology. However, those nasties don't seem to support routed ports.How can I have a routed port on my cisco switch and a standard access port on the BNT and still establish an adjacency with an SVI? I am running OSPF, but I am labbing this in my home lab with 2 x 3550s and EIGRP.

Mar 25, 2012I have an environment where i have two nexus 7010 switches, along with 2 nexus 5510's. I need to run OSPF as a layer 3 routing protocol between the vpc peer links. I have 1 link being used as a keep alive link, and 3 other links being used as a VpC link.
1) Is it best to configure a separate Vpc VLAN i.e 1010

3) just have the management address as the peer ip's.
Cisco Switching/Routing :: 881-K9 - Unable To Use RIP Protocol
Jan 10, 2013I have bought Cisco ISR 881 C880DATA-UNIVERSALK9-M with c880data-universalk9-mz.150-1.M7.bin ios.
command "show ver" tell me:
License Information for 'c880-data'
License Level: advsecurity Type: Permanent
Next reboot license Level: advsecurity
So I have advsecurity. On cisco site there was a thing URL
"Table 5. Cisco IOS Software Features on Cisco 880 Series: Advanced Security Feature Set (Default)"
that tell me I have RIP protocol to use. But when I type "router rip" command and sub router sommands like: network, passive-interface, redistribution. There are no in runnning-config such things after all I've done. It have not been saved.
then the command "show licence":
#show license
Index 1 Feature: advipservices
Period left: Not Activated
Period Used: 0 minute 0 second
License Type: EvalRightToUse
License State: Not in Use, EULA not accepted
License Count: Non-Counted
License Priority: None
I need even RIPv2 to have simple routing information to exchange.
And I don't know. Cisco 880 series is G2 or G1. Cisco ISR beginning from 890 series is G2. About 880 I don't know. There no informanion about it or at least I have not found it yet. On one 891 is the same problem. When I type "router eigrp 1" everything is great. But when "router rip" - do no work.

Cisco Switching/Routing :: UC520 / Forward One IP To Another?
Jun 18, 2011I have a server that I lease that is hosted at a datacenter. Our company is going to lease a half rack and put our own equipment in it as well as a disaster recovery site. The problem is that the one server I mentioned has SQL on it and we have applications that were devloped in house ages ago that hit that SQL instance. Those applications are hard coded to the IP address of that server. We could just change it in the code, but the source code for one of the applications have disappeared over time. Now that you know my situation, my question is this. Can I make a NAT rule or something that says when traffic is destined for xxx.xxx.xxx.123, to re-routes it to xxx.xxx.xxx.321? Currently our endpoint device here is a Cisco UC520. The other end we have no control over.

Cisco Switching/Routing :: Transfer Files Between Two N5ks Via Mgmt0 Using TFTP Protocol?
Jun 8, 2012Is there a possibility to transfer files between two N5k's via mgmt0 using TFTP protocol?
Source: One N5k's mgmt0 interface
Destination: Another Nk5' mgmt0 interface
I know when issuing "copy bootflash tftp" or vice versa, I need to specify management VRF. But how do I specify to be TFTP itself sourced from mgmt0 interface in NX-OS? From IOS I was used to use "ip tftp source-interface <interface>", but in NX-OS I have only Ethernet or Loopback as an option.
According to NX-OS Unicast Routing Configuration Guide (Configuring Layer 3 Virtualization) the answer should be in N7k configuration guide, but I didnt find it there either...
