Aldore R. Landry was convicted following a guilty plea of possession with intent to distribute cocaine in violation of 21 U.S.C. § 841(a)(1) and of possession of a firearm by a convicted felon in violation of 18 U.S.C. 922(g)(1) and sentenced to 71-month concurrent terms of imprisonment. As the Government argues, Landry executed a knowing and voluntary waiver of his right to appeal his sentence, with limited exceptions, and thus is barred from *778challenging his sentence on appeal. See United States v. Robinson, 187 F.3d 516, 517 (5th Cir.1999). Accordingly, we do not address Landry’s waived sentencing guidelines argument. See United States v. Portillo, 18 F.3d 290, 292-93 (5th Cir.1994).
Landry appeals the district court’s denial for lack of jurisdiction of his motion to reconsider sentence. The district court may modify the imposed term of imprisonment under limited circumstances. 18 U.S.C. § 3582(c). Landry argues that his motion to reconsider sentence was not filed under the authority of Fed.R.Crim.P. 35 but, rather, was a “common law” motion to reconsider over which the district court had jurisdiction. The district court did not err in denying Landry’s motion to reconsider sentence. See United States v. Early, 27 F.3d 140, 141-42 (5th Cir.1994).
Accordingly, the district court’s order denying Landry’s motion to reconsider sentence is AFFIRMED.
