I have encounterd a broplem on my Cisco 805 model.
When i use the command "show ip interface brief" the status shows "up" but the protocol is "down" on my serial interface.
The link between my to sites is down after this happend.
I have configured a vlan interface on a 3750 switch. there is aprox 4Mb active traffic flowing through the interface, but when I do a "show interface vlan (vlanid)" the output show zero bits in and zero bits out. Its a typical L3 config with one IP on the vllan interface acting as the gateway for the VLAN devices. Is this a normal behaviur ? and if so is there any way to get the traffic in/out stats. The end PC/devices are connected to this switch via an L2 TRUNK and I dont have access to the L2 switch on which the actual devices connect. so cant get the real time stats of those interfaces.

We are using 3825 Cisco router with IOS version 12.4(24)T2. The unknown protocol drops on our GigabitEthernet0/1 interface is increasing. This interface is connected to our modem. What could be causing this unknown protocol drops?

I'm troubleshooting a 3750 switch stack problem where computers are showing input and CRC errors. I'd like to be able to execute a "show interface" command that will show me only the line showing the switch port and the line showing the input errors, but so far I can't figure out a way of combining those two parameters.
If I do "show interface | include Ethernet[0-9]�" I get all the lines showing the port numbers:
GigabitEthernet1/0/1 is up, line protocol is up (connected)
GigabitEthernet1/0/2 is up, line protocol is up (connected)
GigabitEthernet1/0/3 is up, line protocol is up (connected)

any VLAN interface once administratively down or simply down shows on "show interface status" output as VLAN.While it supposed to show "Routed". However once the port is up it is shows "routed" like it should.
Facing issue with 2960G switch , where its do not display "logging trap informational " in show running and show startup .where its showing all other levels from 0 to 5 and 7 after configuration and save commands. [code] after config getting saved , it do not shows in show runn or in show startup while for all other levels it do show the config lines .I tried the same on 12.55.SE release also but its same results . Is this a limitaion of this platform, is there any doc explaining the same for reference. [code]

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 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
2) Is it best to configure a vrf context keep-alive
3) just have the management address as the peer ip's.
I 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.
When I config BGP on my 3750X Switch, it show error as below:
protocol not in this image
should I need to upgrade the IOS or Where I can found a supported image (support BGP)
I 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?
View 1 Replies View RelatedI am trying to review the port-channel configuration on a 6500 series. I am issuing the "show etherchannel summary" command and the out put shows the Group, Port-Channel, and Ports. It does not show me the protocol that is in use such as PAgP or LACP. Does this have to do with the Etherchannel in the "On" mode rather than "active", or "Auto"?

1. is rapid-pvst the best spanning tree protocol to use? on some switches we have pvst (not rapid)
2. do all switches in the LAN need to use the same protocol?
3. does line 3 :priority 24576 mean that someone set tis switch as root manually? how can one further enforce the backbone as root (so noone adds a old switch with lower root id)

Currently our Cisco 3750 have one interface (port 1) that connected to our provider (Internap) with the IP 66.150.7.68 assigned. Now we want to upgrade to dual handoff L3 protocol. Below is the network configuration from Internap.

I'm trying to upgrade NBAR protocol pack on my Cisco 1941 router, so i downloaded new NABR protocol pack (version 4.0.0) and transferred it into router flash via tftp. When i try to apply new protocol pack with command : ip nbar protocol-pack flash:[protocol-pack-name]

My Company use Core Sw 4507R-Sup 7L-E with Enterprise Services License. I has upgraded to use iOS cat4500e-universal.SPA.03.03.01.SG.151-1.SG1.bin
When I use match protocol in class-map, there are only about 10 protocols, and not have those ones I need. I intend to expand the list of protocols to do some Policy-map by loading PDLM. But 4507 is no longer support NBAR. So do we have another way to set Catalyst 4507R with Sup 7L-E recongnize more protocols in match protocol command?
Is 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...

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.
I have a Cisco ASA 5505 and I have my internal and external interfaces configured but I currently cannot ping from the inside to an IP Address on the outside.

When I ping 4.2.2.2 for example I get:
Destination host unreachable
Do I need to add a static route from my inside interface to my outside interfaces?
