Cisco Switching/Routing :: 6590 / Mac Address Not Showing Up Without Specifying The Interface
Apr 23, 2012
I always though that sh mac address table dynamic interface xx/xx/xx was a subset of "sh mac address table" 6590 Version 12.2(33)SXI I have two mac addresses on downstream switches that will only show up when using
sh mac address-table dynamic interface Te4/10
* 903 0050.77a9.6e3c dynamic Yes 0 Te4/10
* 903 0050.77a9.5766 dynamic Yes 0 Te4/10
when using "old faithful"
sh mac address-table | inc 6e3c
*nothing*
or
sh mac address-table dynamic | inc 6e3c
*nothing*
nothing shows up?this vlan has no layer three interfaces
We have 3 Cat 4500 switches on three floors teh 3rd floor switch connects to the 2nd and 4th floor switches ,but we are receiving an alert from monitoring tool that " Interface(314) Backup-1Gb-Ring is Down at least 2 min on Switch: SOM500-4510-3FL the following output from "sh int status module 1 " shows the int 1/3 and 1/4 are 'inactive'local IT guy said If the status is inactive,the ports cannot be used and might lost the capability when he added 48-port blade into the 10th slot.

I am trying to configure a 4507 R chassis with Dual SUP but i cannot see teh switchpot mode trunk encapsulation dot1q?
I have typed:
interface GigabitEthernet5/1 description DOWNLINK toxxxxxx switchport mode trunk channel-group 11 mode on ! I have have searched all other commands and sub-commands but could only find dot1q-tunnel which I beleive is for QINQ or some QoS featues and lot for L2 encapsulations?
the puzzling is:
XXX-Core4507#sh int gi5/1 trunk
Port Mode Encapsulation Status Native vlan Gi5/1 off 802.1q notrnk-bndl 1 (Po11)
when I connect the dostribution switch a 3507 to this int gi 5/1, both interfaces do come up?
we have 6500 cisco switch as a backbone switch in universty. When ı want to look mac addres table , it does no show all mac address.ı mean if ı type ;show mac address-table there are not all mac address.
I'm currently working on a plan to migrate our 6500's over to our new 7010's. At the time of the migration I want to tighten up our OSPF design and configure OSPF for "passive-interface default" then allow only those interfaces that should have OSPF neighbors to send the hellos. The issue is that the command is not showing up under the OSPF process. What's even more interesting is that the Nexus 5.x Unicast Routing Configuration Guide shows that the "passive-interface default" command should be an option to enter.
I'm currently running version 5.1(4) (though looking to upgrade to 5.2 during my migration testing). I would rather configure the passive-interface via the routing process versus having to enter it on every interface.
I have a cisco 878 router and I can’t assign ip address to it’s fast Ethernet interface. When I assign ip address give me this message: “you can not assign ip address to layer 2 interface”.
But I can not understand why give me this alert when I use a layer3 device?!
I have a Cisco Catalyst 4506-E Swtich,I configure it as a DHCP and gw for the Wireless Cisco AP through the WLC 5508,the DHCP pool reached the maximum limit I run the Show ip dhcp pool (pool name) it's show the below result

Having 2 router with 2 sub interface configured with HSRP. The server sending the data have the route default gw xxx.xxx.xx.252 HSRP address. But on of the routers did got HW problem so we did shut it down, R2 with IP xxxx.xxxx.xxxx.251, problem so the traffic didn't go there correct when was using the HSRP address some packaged went there but not all of them no blocks in the logs. But then we did change the server direct to to the working router R1 xxxx.xxxx.253 everything did start working fine again. was working fine. Logs i got in the router was max tcp half-open connections.
I am wondering if something wrong in the configuration below and why the traffic didn't got there correct when using the HSRP address. Its working fine when using R1 IP address. The devices are 2 Cisco 2620 routers.
R!1 interface FastEthernet0/0.192 description Prod_Inside encapsulation dot1Q 192 ip address xxx.xxx.xxx.253 255.255.255.192 ip access-group Inside_Outside in ip verify unicast reverse-path no ip redirects [code]...
I have just updated a VLAN interface on my router. I have two 6500's with GLBP configured. The particular interface had a primary and secondary IP address. I shutdown the interface on one router and deleted the secondary address then assigned the orignal secondary address to be the be the only address associated with the interface and enabled the interface and it came right back up...all looks good. I proceeded to do the same thing to the other router and once again all looked good. Now, I am able to PING the devices in the subnet from router, but am unable to ping them from any place else. [code]
i am gettinfg the following error while copy the configuration from 6590 to tftp server %Error opening tftp://x.x.x.x/yyyy (Timed out)
1) The file is getting created in the TFTP server but it is empty and a Zero Kb file
2 ) I can able to ping to the FTTP server from the switch
3) I can able to ping to switch from the tftp server
4) The same tftp server is working wih all another Switches (i have checked with anothed TFTP softwares also but the same problem)
5) The switch is in the different subnet, the switch is having several SVIs. Also Configured the command "ip tftp source interface vlan361" (This interface can able to ping from the tftp server and also can do extended Ping from this IP to the tftp server)
6)The communication between Ftp server and the switch want to cross Point to Point WAN link (Another switches can communicate with the tftp server through the same wan link)
7)If i run FTP server on the same System and try to copy running config from 6509 to FTP some times it is working and some times it is giving the error.
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. I had this setup and working and I have another set of equirement that I am replacing that is working with my service provider so I know it is a configuration issue. 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?
I hav e a 3750X Cisco Switch (WS-C3750X-48T-S) It is two Ethernet base SFP installed and working fine at slot 1 & 2, Now i am trying to install GLC-SX-MM in 3rd and 4th slot, but its not coming up, showing not present?

No date in the TOP-N Interface Errors portlet showing in LMS 4.1, but data for TOP-N Interface Utilization is displayed like expected. The Interface Errors poller show active(without errors) with same Instances as Interface Utilization.
For an assignment in a class I am taking I created a simple network using GNS3 and set up static routing. Everything works fine, I can ping all of the hosts. One of the questions I am supposed to fill out is what happens when I use the "show ip route" and "show ip protocols" commands. When I use "show ip route" I get what seems to be the correct output. However when I use the "show ip protocols" command nothing happens. No output, no error, no nothing. It just goes right back to the prompt. This happens exactly the same on both routers in my network. incase it matters the router is c3640.
PS. would the output be non-existent because I have not set up any ip protocols. In a similar assignment I set up rip and when I used "show ip protocols" i did get what appeared to be the correct output. However I didn't write it down and when I put in the command again about an hour later after I took a break I also did not get an output until I re-entered the rip related commands.
We ordered the wrong part number for a Cisco 4506 non-E chassis, the part number is: WS-X4624-SFP-E and the device is showing "Unsupported module"; What would the part number be for the non-E? WS-X4448-GB-SFP,Catalyst 4500 48-Port 1000Base-X (SFPs Optional) ?
I am runing 802.1x and MAB authentication of devices connected to a 3560 switch (in test). When I run 'terminal monitor' I am getting alot of authentication fail-msg. Is it possible to get the switch not to show them? I have to do some debugging on SNMP and DHCP to be able to figure out why I get these msg, but since the switch is blasting out so many auth-msg it is hard to see the debug messages. [code]
Looking at the following output (show interface status) from one of our 4507s I see gig interfaces 3/2 to 3/6 are all trunked (dot1q). When I look at a show run they do not show as trunked. They should indicate switchport trunk encapsulation dot1q and switchport mode trunk (as does interface gig4/2). I have seven other 4507s all running the same IOS: 12.2(25)EWA8 and they all show the same information in show run and show interface status (as far as trunked goes). This is not a problem as I know the interfaces are trunked and working properly I am just puzzled as to why I see this difference.
Here is the sho int gig3/2 trunk. It looks like you are correct. I did not realize some were set to trunk mode on and others were not. I would think the running config would still show the port using dot1q but I guess not.
when I do a show module in my cat 6509, the standby sup is saying unknown, it has the same IOS as the primary card. what does this mean? are there any tests I can run on the card?
Cisco Catalyst 6509 Chassis.We have moved a line card from slot 8 to slot 6, but config remains for the line card in slot 8 and nothing is seen in slot 6.
We are running on IOS Verison 12.2 (33SXH2A) i.e. VSS.Blade model number is WS-X6748.
We have several stacks of 3750 switches where this problem is occurring. All of the switches are running IOS version 12.2(50)SE3. (Yes, I know it's old.)
We're seeing inconsistency in how the stack reports members when issuing the following commands:
sow switch show version show inventory
Not all members are showing up in the output of the "show version" and "show inventory" commands. For example:
HUNTI-WV-WDAC03#sh switch H/W Current Switch# Role Mac Address Priority Version State ---------------------------------------------------------- 1 Member 108c.cff2.ea00 15 0 Ready 2 Member 8cb6.4f0a.a600 1 0 Ready *3 Master 8cb6.4f0a.9c00 1 0 Ready (all three switches in stack are displayed)(code)
We have a C4500 with 2 sup V which is showing high CPU values sometimes.When this occures, the switch shows 95-100% for total cpu for a few hours at a time.show proccesses cpu shows process Cat4k Mgmt LoPri with an unusual cpu value of 65% The show platform heath command gave me a high reading for K2FibFC DelFlow which is about 50% at this peak but is normaly around 1%?
what the process K2FibFC DelFlow means and what could be the cause of this peak?
I am using a Cisco ME 3800 switch with 24 Gig and 2 Tengigabit interface. But after configuring the Tengig int with ip add and negotiation it is no know visible in the switch. Instead TenGig I am seeing two (Gi0/1 and G0/2). Not even showing the Tengig in the running config.
I have an 891w that started acting up recently. Radio dot11 0 is reporting its a b radio. When it is actually an n 2.4 radio. Of course that radio is not allowing any clients to connect to it at this time. I have tried updating the firmware to the latest, tried a hardware reset but still a nogo.
sh interface output.

I have installed a Catalyst 2960-S and a 3750-X-12S and I am trying to setup a VLAN 51 for some VoIP phones. I have added the VLAN as an interface on both switches, but the 3750 is not showing VLAN 51 as active when i do a show vlan. Also, it omitts showing Gi1/0/1 & Gi1/0/3 which are uplinks to 2960-S switches plugged in and working on VLAN1.

We have supplied Cisco Swtch 2960 with gig SFP modules. It is working fine. However, when I do a show inventory it show proper part no. for the switch chassis but for the GLC T module it shows as unspecified in the PID column.
I just upgraded my power supply's from 2500Watts to 4000watts, however the show power still shows 2500watts.how do i make the 6513 recongize the change? I do have 250volts at 30 amps connected to each power supply.
system power redundancy mode = redundant system power total = 2331.00 Watts (55.50 Amps @ 42V) system power used = 1741.74 Watts (41.47 Amps @ 42V) system power available = 589.26 Watts (14.03 Amps @ 42V)
