I mean those equipment in Sandbox environment. it's pre-setup topology for testing. not sure why Cisco doesn't have technical support channel for Sandbox.

Hi everyone, i got the solution for this problem. and discovered that: Only 2 HWIC or EtherSwitch network modules can be used in this platform and to let them communicate with eachother we have to stack them physically by an ethernet cable to use one port on each card as a trunk. and also we have to issue the command switchport stacking-partner on these trunk port to let the two HWIC cards have L2 connectivity. please rate if you find it helpful. thanks!

Hi Leo, please find the boot process output that pasted below. BTW when i connect two hosts on the same HWIC they reach each other but the problem is when i connect them on different HWIC cards. thanks IOS Image Load Test ___________________ Digitally Signed Release Software program load complete, entry point: 0x81000000, size: 0x5e65400 Self decompressing the image : ############################################################################################################################################################################################################################################################################################################################################################################################################################################################################################################################################################################################################ [OK] Smart Init is enabled smart init is sizing iomem TYPE MEMORY_REQ HWIC Slot 2 0x00200000 HWIC Slot 3 0x00200000 Onboard devices & buffer pools 0x0228F000 ----------------------------------------------- TOTAL: 0x0268F000 Rounded IOMEM up to: 40Mb.

Hello, i have a 2901 router (IOS version 15.3) and after i plugged the Ethernet module into one of its EHWIC i found that the router doesn't detect it and the other router detected it and no traffice is passed through it. does any one know why that happened. BTW this Router should support 2 4-port Cisco Gigabit Ethernet EHWICs. thank you! Makar

Hello, i've been implementing our DMVPN tunnels and i have on tunnel doesn't form its crypto sa or peer. below is the output of some debug regarding the crypto isakmp negotiation to establish IPSEC tunnel. by the way, before i assigned the tunnel protection command to the interface tunnel i've checked the nhrp peers and made sure that the nhrp peer for that end point has been established successfully. so i think the problem in crypto config. please find the output below of my debug and let me know why they don't form crypto peers. thanks and appreciate your quick response. rtrq1301#sh crypto isakmp sa IPv4 Crypto ISAKMP SA dst src state conn-id status 64.x.x.x 24.x.x.x MM_NO_STATE 0 ACTIVE 65.5.x.x 24.x.x.x QM_IDLE 1012 ACTIVE 65.5.x.x 24.x.x.x QM_IDLE 1013 ACTIVE IPv6 Crypto ISAKMP SA rtrq1301# debug crypto isakmp Jun 24 11:05:54: ISAKMP:(0): retransmitting phase 1 MM_NO_STATE...

Hi Shine, thanks for your reply! i'm using two tunnel interfaces on the same source physical interface with different destination ip addresses and different NHRP IDs and also different GRE IDs. so in this case i should use share word at the end of this command or not? thank you! Labb

Hello, what the impact of share word when i type it at the end of this command under interface tunnel mode in DMVPN configuration? tunnel protection ipsec profile share in other words, if i have two tunnels on the same physical interface with two different clouds and didn't type share word at the end of that command will cause any problem communicating with their peers? please treat this as urgent. thank you for your help!

fischer, thanks for your reply. acually i understand it is good thing for generating a TCN but in my scinario it happens continuously and also the major issue i have is the random brownout in my network. so one of the causes which i'm suspecting is STP storm that might happens from continuous flapping links like fa4/40 and then makes the trunk links in this VLAN to go through the blocking state at the point of the brownout. does what i say make sense or i'm confused?

hello, my client has a switched network of 2 core switches of 4506 and 6 access layer switches most of them are 2960s. every few days my client experience a random brownout in the network for few minutes. today they had a brownout for few minutes started at 3:14pm. i took a look at the trap report i found continuous events of bridge topology changes. i attached this file i hope any one has experienced this before to share his knowledge and experience. regards, Makar

most of the switches have been up for 43 days. these ports connected to desktop coputers or servers ( but i don't know yet what kind of applications installed on them. attached is the top interfaces with errors for yesterday. the cause of these errors might be DHCP snooping or kind of broadcasting? because i checked the utilization it looks normal most of the times. thanks for sharing your knowledge and experience. regards, Labib

Hi Leolaohoo, thanks for your reply. attached is the show commands for three interfaces i noticed big numbers of errors. Gi/3/11 and Gi3/14 connected to fiber cable but fa4/40 to rj45. all of them in vlan1. i'm suspecting the probably reason for errors on Gi3/11 and Gi3/14 the fiber cable should be cleaned or replaced. but what about Fa4/40. and is the huge number of these errors on these interfaces causing a brownout in the network?!. i'm confused a little bit. regards, Labib
