Anyone know the maximum number of IPv4 routes supported per VRF (using VRF-Lite) on a Cisco 3750E stack (two switches in the stack). The current SDM template is 'desktop'.
View 2 RepliesI'm using a Catalyst 4500 switch (C4507R+E) with Sup 7E. Cisco Datasheet of this switch says that it can learn maximum 256K IPV4 routes. Currently it just learns 10330 ipv4 routes. However when I show platform hardware ip route summary, it seems that the FIB is just free 100K routes as below output:
Entity total used free util%
Entries 260096 10332 249764 3
UC Ipv4 110592 10331 100261 9
unused 147456 147456 0 100
My question is: Can I make use of all 147456 unused routes? Or these ones have to use for any special purpose?
I cant find the maximum number of vrf supported on a 3925E ?

View 1 Replies View RelatedIs there a way in EIGRP to prefer external routes versus internal routes. EIGRP always picks up internal routes as long as they are available, no matter if external routes have better metric. Our Scenario is that we have DMVPN hub and spoke topology running EIGRP 101. The Core routers also on EIGRP 101 prefer EIGRP 101 routes. We have the new MPLS network running BGP and redistributing these BGP routes into EIGRP 101. The core routers prefer EIGRP 101 routes (internal) to redistributed BGP (external) routes.

have 2 3750's one is an 3750E the other one is a G... Since they are 2 different versions Do I need to correct ios for each for example my 3750E switch i would have
IP BASE
c3750e-ipbasek9-mz.122-53.SE2.bin and for my 3750G switch should i use
IP BASE
c3750-ipbasek9-mz.122-53.SE2.bin
Which would be 2 separate images

View 1 Replies View RelatedWe're seeing "OutDiscard" error on a LAN switch connected to newly migrated Cisco IP phones. All the other error counters are clean except for the OutDiscard. (please see attached "show int count err" output.) [URL].
According to the link above, the common cause of such discards can be to free up buffer space.(Am I seeing a switch buffer issue?) How to identify/resolve the cause of the OutDiscard.The switch is 3750-E running c3750e-universalk9-mz.122-44.SE6.bin
I am seeing on my 3750E series switches (WS-C3750E-48TD). I have multiple VLANs configured on here, one which is used as a 'workstation' VLAN. I have an inbound ACL applied to the VLAN interface *(int vlan 50 to be exact). This list is admittedly long at roughly 6000 ACE's. Now I just recently installed these switches as they replaced some 4507R switches which we moved to our new centralized DC. Here is the issue I am having. This same ACL was applied to the same VLAN interface on the 4507s when they were doing the work of the 3750s. What I used to be able to do was actually edit the ACL by removing it with no ip access-list extended WS-In and then followed up by the ip access-list extended WS-In ......and the lines I wanted in the ACL. I know I could use the line numbers to edit the ACL but this worked OK for me. When I would do this on the 4507R, the ACL was still applied to the interface but traffic never seemed affected by the removal and re-adding of the ACL. I did this by copying and pasting the ACL into a terminal window. It seemed as though on the 4507 the ACL was not compiled until the entire thing was in loaded in and therefore traffic was not processed by the ACL until the load was done

When ip generate traffic to this server this mac address appear in table again on shot time (less than 10 seconds).
I had a lot of problems with TCAM table in the past and made changes in SDM ended whit that. But now want to be proactive and anticipate the problems in my TCAM table.
If the my template is "default desktop" they support a number of indirect IPv4 routes of 2k. I wanna know automatically by my management tools if this number reaches 1.9k.
That way I can take corrective actions before the problems starts on my network.

View 3 Replies View RelatedI am not able to find the exact bug for Cisco 3750E stack - Debug Exception (Could be NULL pointer dereference) Exception (0x2000) error. Closest i can find is CSCsa72400 which only affects ver 12.2(20)SE4.All the stacks (3 switches) are running 12.2(50)SE3, It appears that the switch 1 crashed and reloaded. My hunch is its software but i cant find any related bugs. It could be hardware issue as well ?
View 4 Replies View RelatedI have a device which will be sending voice and data packets and is able to mark the packets with DSCP values. Voice, 18 and Data 42.If this was a straight through network, I'd be clear on how to handle this, but.....I will be putting this traffic into a VLAN to isolate it from some other traffic on the network. What is the best way to prioritize this traffic inside the VLAN? Will the Cisco switch look at and respect the DSCP values inside the VLAN and prioritize accordingly inside the VLAN? Or, do I need to do some sort of DSCP to 802.1p mapping? Another option I would be fine with would be mapping the DSCP values for voice and data to two different VLANs and then giving the voice VLAN priority over the data VLAN .... I'm using 3750E switches.

2x10Gbe uplinks from EMC NAS
At a basic level, we have found that the 10Gbe uplinks have slow read performance with or without a port-channel configured (2-3 minutes for a 700MB file to desktop from the NAS) We switched back to testing a 1Gbe and the read speed is normal. Another anomaly is Win7 / 2008 machines read speed is fine from the NAS while the 10Gbe uplinks are in production?!
Write speed is great on 10Gbe. Only read speed is affected!! the switch is not reporting anything abnormal. We looked at SMB/SMB2 as another possible cause...
mls qos is enabled on the switch but not sure if this is affecting performance.
Is the ANY config that I need to carry out on the interfaces to get the read speed working as it should for both Win7 and WinXP. (MTU is 1500 throughout the enterprise, NAS included).
I have installed and configured 2 new WS-3750E-24TD in the last 30 days, that have software version 12.5(50)SE2-universalk9, on our flat Development LAN (currently 7 existing WS-3750E-24TD with 12.5(35)SE2-universal)The new switches have shutdown, 1 has shutdown twice and I just had the other one shutdown on the weekend, all the status lights on the left are lit up but no port lights are on, I am not able to console in to the switch all I can do is cycle power. I am planning on upgrading all switches to the latest software release universalk9-mz.150-1SE
could this problem be a version incompatibillity between the switches?
We have many 3750E's and need to use Finisar X2 modules FTLX8541E2. After 15.0(1) IOS upgrade the 3750's now recognize the Cisco part X2-10GB-LRM's, but will not recognize our Finisar modules.
View 1 Replies View RelatedAccording to the following Cisco webpage, cross-stack 10-Gigabit EtherChannel is possible on the 3750 with up to two 10-Gigabit modules, using LACP: url...However, the webpage doesn't confirm if this functionality is restricted to a particular 3750 model, such as 3750E, or if it applies to all models. It also doesn't specify any particular IOS feature set. I've tried Cisco Software Advisor but it doesn't list this feature on either the 3750E or 3750-X. This is possible on the 2960-S switches (i.e. cross-stack 10gig EtherChannel)?
